Failed to take over all threads after multiple attempts.
Hi all Thanks to release this useful lib for check dynamic memory when i tride compile with mingw32(msys2) and use dr.memory to debug
./drmemory.exe /d/static_test/G_memory_test/build/G_memory_test.exe
i got this error
~~Dr.M~~ Dr. Memory version 2.4.0 ~~Dr.M~~ Running "D:/static_test/G_memory_test/build/G_memory_test.exe" ~~Dr.M~~ Using system call file C:\Users\KARTHY\AppData\Roaming\Dr. Memory\symcache\syscalls_wow64.txt <Application D:\static_test\G_memory_test\build\G_memory_test.exe (12480).

this is my CMakeFile and source file, thanks a lot!
