/* * From: Todd Owen <towen@lucidcalm.dropbear.id.au> * To: pthreads-win32@sourceware.cygnus.com * Subject: invalid page fault when using LoadLibrary/FreeLibrary * * hi, * for me, pthread.dll consistently causes an "invalid page fault in * kernel32.dll" when I load it "explicitly"...to be precise, loading (with * LoadLibrary) isn't a problem, it gives the error when I call FreeLibrary. * I guess that the dll's cleanup must be causing the error. * * Implicit linkage of the dll has never given me this problem. 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; }
