CJ: v22.0.0
VisualStudio: 2022 (17.11.5) Windows: 11 I am creating numerous worker threads using _beginthreadex and terminating them with _endthreadex(0) and CloseHandle(). When taking a memory snapshot in Visual Studio, a memory leak of 480 bytes per thread occurs at MyApp.exe!_AFX_THREAD_STATE. The call stack is as follows, confirming that the memory was allocated by the Toolkit during thread creation: kernel32.dll!0x7ff96021257d() MyApp.exe!CXTPSkinManagerDetoursApiHook::ThreadProcHook() - Line 591 MyApp.exe!AfxGetModuleState() - Line 314 MyApp.exe!CThreadLocal<_AFX_THREAD_STATE>CreateObject() - Line 200 MyApp.exe!CThreadLocalObjectGetData() - Line 453 MyApp.exe!CThreadLocal<_AFX_THREAD_STATE>::GetData() - Line 179 MyApp.exe!CThreadLocal<_AFX_THREAD_STATE>::operator _AFX_THREAD_STATE *() - Line 191 It seems that using AfxBeginThread instead of _beginthreadex can avoid this issue My application creates and deletes a very large number of threads, so I cannot overlook this small memory leak. Additionally, the libraries my application depends on also seem to create threads, making it impossible to replace all thread creation with AfxBeginThread. Is there any workaround for this issue? Regars, Shinya

Hello Shinya,
Unfortunately it is not clear what exactly is going wrong. Can you please provide more detailed information. If it cannot be re-produced in any of our sample applications provided I would appreciate you sending a sample application so that we could debug it. Regards, Artem Gontarenko |

Thank you for your response.
By calling AfxTermThread() at the end of threads created with _beginthreadex and CreateThread, I was able to solve the problem. Thank you. |
