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:


#include <windows.h>
int main() {
  HINSTANCE hinst;

  hinst = LoadLibrary("pthread");
  printf("hinst == %d\n", hinst);
  printf("press a key to keel over...\n");
  getch();

  FreeLibrary(hinst);
  return 0;
}


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.

Sorry, but I have no idea how to fix the problem.  It's taken me long
enough to track it down this far.

Todd.
