36  * Subject: invalid page fault when using LoadLibrary/FreeLibrary
37  *
38  * hi,
39  * for me, pthread.dll consistently causes an "invalid page fault in
40  * kernel32.dll" when I load it "explicitly"...to be precise, loading (with
41  * LoadLibrary) isn't a problem, it gives the error when I call FreeLibrary.
42  * I guess that the dll's cleanup must be causing the error.
43  *
44  * Implicit linkage of the dll has never given me this problem.  Here's a
45  * program (console application) that gives me the error.
46  *
47  * I compile with: mingw32 (gcc-2.95 release), with the MSVCRT add-on (not
48  * that the compiler should make much difference in this case).
49  * PTHREAD.DLL: is the precompiled 1999-11-02 one (I tried an older one as
50  * well, with the same result).
51  *
52  * Fascinatingly, if you have your own dll (mycode.dll) which implicitly
53  * loads pthread.dll, and then do LoadLibrary/FreeLibrary on _this_ dll, the
54  * same thing happens.
