If you wish to use thread you need to go get the Mingw32 gcc compiler which uses the native CRTDLL.DLL which is thread safe. You can find the Mingw32 gcc compiler via Colin Peters' page. URL is listed below. ---"Gilbert W. Pilz Jr" wrote: > > Has anyone else seen this problem ? > > I'm trying to debug a simple program that creates multiple threads using > CreateThread().
