Hi there,
I have spent some time tracking a crash occuring with "Virtual Midi
Controller" ( http://www.soundcosoftware.com/vmc.htm )
Apparently, this virtual midi device is still calling the callback
(once) after the stream has been closed, so I am not sure if portmidi is
really the one to blame. The callback is called with wMsg==MIM_CLOSE ,
and it causes a crash because the callback is protected by a critical
section which have been destroyed.
So I suggest patching winmm_in_callback with a "if (wMsg == MIM_CLOSE)
return;" placed before the EnterCriticalSection code. At least it seems
to work well here :)
btw, about pm_dll.dll : I don't use it in our host, and so far I have
never experienced/heard of windows crashes so I would say it can safely
be omitted, at least for winxp and vista.
Best regards,
Julien Pommier.
