Here's a * program (console application) that gives me the error. * * I compile with: mingw32 (gcc-2.95 release), with the MSVCRT add-on (not * that the compiler should make much difference in this case). * PTHREAD.DLL: is the precompiled 1999-11-02 one (I tried an older one as * well, with the same result). * * Fascinatingly, if you have your own dll (mycode.dll) which implicitly * loads pthread.dll, and then do LoadLibrary/FreeLibrary on _this_ dll, the * same thing happens. * */ #include "test.h" int main() { HINSTANCE hinst; assert((hinst = LoadLibrary("pthread")) != (HINSTANCE) 0); Sleep(100); FreeLibrary(hinst); return 0; }
