* SF Bug Tracker [ 2876374 ] Access Violation when compiling with Visual Studio 2008

Hi,
I am one of the devs of the MorphXT project and I use this lib in some
other of my projects, too. When I tried to upgrade the lib earlier for one
of my projects I had to realise that something did not work at first and
while most of the things were reasonably ease to be fixed. Now, the last
thing I encountered was not so easy to fix and I am uncertain if my fix is
any good so I'll just post it here and wait for some comments.
The problem was that I got an Access Violation when calling "UpnpInit". It
would call "ithread_rwlock_init(&GlobalHndRWLock, NULL)" which eventually
led to calling "pthread_cond_init" and I got the error notice at
"EnterCriticalSection (&ptw32_cond_list_lock);". It appeared that
"ptw32_cond_list_lock" was NULL. Now, I found two ways to fix this. Firstly
moving the whole block after at least one of the "ThreadPoolInit" calls
will fix the issue. Secondly, you could add:
#ifdef WIN32
#ifdef PTW32_STATIC_LIB
// to get the following working we need this... is it a good patch or
not... I do not know!
pthread_win32_process_attach_np();
#endif
#endif
right before "ithread_rwlock_init(&GlobalHndRWLock, NULL)".
Just so you know, I am using libupnp 1.6.6 and libpthreads 2.8.0 and both
are linked static into the binaries. I am currently using Visual Studio
2008 for development with Windows being the target OS. Any comment at your
end?
Regards, Stulle
