pthread_exit() does not call the cleanups

pthread_exit() does not call the cleanups

[Kereszt]

Hello,

I've found that with pthread-win32 the pthread_exit() does not call the
previously pushed (pthread_cleanup_push()) cleanup routines. I've just tried
it on a linux box and it works as documented (does the call).

I'm a bit newbie to pthread so it might be my fault. I've attached a little
sample code which reproduces the problem.

Please, tell me what's the deal!

Thanks,
Laszlo

My fault. False alarm.

At some point I failed to define __CLEANUP_CXX, and pthreadVSE doesn't work
fine with C++ exceptions enabled (VC++ compiler option: /GX or /EHsc). MSDN
says it can be mixed.. mostly.. but.. Unfortunately, the latest pthread
release doesn't contain precompiled VCE binary.. I tried it from the
previous (2004-06-22) release. Finally, I successfully compiled a fresh one
with VS7. I am simply unable to get work nmake, some PATH or whatever seems
to be missing but I cant hunt forever. I'm from UNIX.. it looks much cleaner
for me..

Conclusion: Now, it works.. Maybe, this will help others browsing mail
archives :)

Thanks and best regards,
Laszlo
