In this part of the documentation we will describe how to use the Visual Leak Detector to detect memory leaks in the C++ code. ## Using the Visual Leak Detector Looking for memory leaks in SimModel when used in PK-Sim (MoBi, etc. - same procedure) 1. Install **Visual Leak Detector for Visual C++** (VLD) from \~\~ EDIT 2022: VLD development continues now here: (latest release: ) 2. Open SimModel solution in Visual Studio and uncomment the line `#include ` in **src/OSPSuite.SimModelNative/src/Simulation.cpp** 3. If VLD was installed NOT into the default path: open project settings of **OSPSuite.SimModelNative** and adjust the paths in the Debug-configuration ![grafik](https://user-images.githubusercontent.com/25061876/74615676-4154c080-5123-11ea-9d2a-b8db8732d4cf.png) 4. Build the Debug version of **OSPSuite.SimModelNative** 5. Copy **OSPSuite.SimModelNative.dll** and **OSPSuite.SimModelNative.pdb** from *\\Build\\**Debug**\x64* into the PK-Sim folder 6. Copy the ***Debug*** version of **OSPSuite.FuncParserNative.dll** and **OSPSuite.FuncParserNative.pdb** from the corresponding Nuget package into the PK-Sim folder 7. Copy the ***Debug*** version of **OSPSuite.SimModelSolver\_CVODES.dll** and **OSPSuite.SimModelSolver\_CVODES.pdb** from the corresponding Nuget package into the PK-Sim folder 8. Open "**C:\Program Files (x86)\Visual Leak Detector\vld.ini**" in a text editor and set * `AggregateDuplicates = yes` * `ForceIncludeModules = `\ E.g. to profile FuncParser as well: `ForceIncludeModules = OSPSuite.FuncParserNative.dll` * `ReportFile = ` Leak report will be created here\ E.g. `ReportFile = C:\Temp\SimModelLeaks.txt` * `ReportTo = file` or `ReportTo = both` * `StackWalkMethod = fast` 9. Start PK-Sim and perform actions you would like to profile (run individual/population simulations, perform sensitivity analysis, parameter identifications, ...) 10. Close PK-Sim. Leak report is now available in the `` defined in vld.ini

[Options] ; The main on/off switch. If off, Visual Leak Detector will be completely ; disabled. It will do nothing but print a message to the debugger indicating ; that it has been turned off. ; ; Valid Values: on, off ; Default: on ; VLD = on ; If yes, duplicate leaks (those that are identical) are not shown individually. ; Only the first such leak is shown, along with a number indicating the total ; number of duplicate leaks. ; ; Valid Values: yes, no ; Default: no ; AggregateDuplicates = yes ; Lists any additional modules to be included in memory leak detection. This can ; be useful for checking for memory leaks in debug builds of 3rd party modules ; which can not be easily rebuilt with '#include "vld.h"'. This option should be ; used only if absolutely necessary and only if you really know what you are ; doing. ; ; CAUTION: Avoid listing any modules that link with the release CRT libraries. ; Only modules that link with the debug CRT libraries should be listed here. ; Doing otherwise might result in false memory leak reports or even crashes. ; ; Valid Values: Any list containing module names (i.e. names of EXEs or DLLs) ; Default: None. ; ForceIncludeModules = OSPSuite.FuncParserNative.dll ; Maximum number of data bytes to display for each leaked block. If zero, then ; the data dump is completely suppressed and only call stacks are shown. ; Limiting this to a low number can be useful if any of the leaked blocks are ; very large and cause unnecessary clutter in the memory leak report. ; ; Value Values: 0 - 4294967295 ; Default: 256 ; MaxDataDump = ; Maximum number of call stack frames to trace back during leak detection. ; Limiting this to a low number can reduce the CPU utilization overhead imposed ; by memory leak detection, especially when using the slower "safe" stack ; walking method (see StackWalkMethod below). ; ; Valid Values: 1 - 4294967295 ; Default: 64 ; MaxTraceFrames = ; Sets the type of encoding to use for the generated memory leak report. This ; option is really only useful in conjuction with sending the report to a file. ; Sending a Unicode encoded report to the debugger is not useful because the ; debugger cannot display Unicode characters. Using Unicode encoding might be ; useful if the data contained in leaked blocks is likely to consist of Unicode ; text. ; ; Valid Values: ascii, unicode ; Default: ascii ; ReportEncoding = ascii ; Sets the report file destination, if reporting to file is enabled. A relative ; path may be specified and is considered relative to the process' working ; directory. ; ; Valid Values: Any valid path and filename. ; Default: .\memory_leak_report.txt ; ReportFile = C:\Temp\SimModelLeaks.txt ; Sets the report destination to either a file, the debugger, or both. If ; reporting to file is enabled, the report is sent to the file specified by the ; ReportFile option. ; ; Valid Values: debugger, file, both ; Default: debugger ; ReportTo = both ; Turns on or off a self-test mode which is used to verify that VLD is able to ; detect memory leaks in itself. Intended to be used for debugging VLD itself, ; not for debugging other programs. ; ; Valid Values: on, off ; Default: off ; SelfTest = off ; Selects the method to be used for walking the stack to obtain stack traces for ; allocated memory blocks. The "fast" method may not always be able to ; successfully trace completely through all call stacks. In such cases, the ; "safe" method may prove to more reliably obtain the full stack trace. The ; disadvantage is that the "safe" method is significantly slower than the "fast" ; method and will probably result in very noticeable performance degradation of ; the program being debugged. ; ; Valid Values: fast, safe ; Default: fast ; StackWalkMethod = fast ; Determines whether memory leak detection should be initially enabled for all ; threads, or whether it should be initially disabled for all threads. If set ; to "yes", then any threads requiring memory leak detection to be enabled will ; need to call VLDEnable at some point to enable leak detection for those ; threads. ; ; Valid Values: yes, no ; Default: no ; StartDisabled = no ; Determines whether or not all frames, including frames internal to the heap, ; are traced. There will always be a number of frames internal to Visual Leak ; Detector and C/C++ or Win32 heap APIs that aren't generally useful for ; determining the cause of a leak. Normally these frames are skipped during the ; stack trace, which somewhat reduces the time spent tracing and amount of data ; collected and stored in memory. Including all frames in the stack trace, all ; the way down into VLD's own code can, however, be useful for debugging VLD ; itself. ; ; Valid Values: yes, no ; Default: no ; TraceInternalFrames = no ; Determines whether or not report memory leaks when missing HeapFree calls. ; ; Valid Values: yes, no ; Default: no ; SkipHeapFreeLeaks = no ; Determines whether or not report memory leaks generated from crt startup code. ; These are not actual memory leaks as they are freed by crt after the VLD object ; has been destroyed. ; ; Valid Values: yes, no ; Default: yes ; SkipCrtStartupLeaks = yes ```
