Hi,
I'm getting pretty stuck on this, so I hope someone may have
a clue.
I ported Csound to Haiku pre-PM, and it works fine there.
When I try to run it in a PM partition it also runs... until I
try to quit,when it locks up hard.
I've narrowed it down to the add-on library I wrote to implement
Haku audio and midi, but I'm actually beginning to think I did
nothing wrong there, and the bug is in the MediaRoster or
somewhere. [Though I'll be happy to be proven wrong...]
I essentially borrowed most of the code from ToneProducer,
and that still runs fine, but it's not a library. My code is dying
when dlclose() is called on it. I'm attaching the debug printout,
which shows that it's hanging in a BLooper Quit() -- apparently
in the MediaRoster.
I sort of suspect MediaRosterUndertaker, as that's been added
since my original code:
http://cgit.haiku-os.org/haiku/commit/src/kits/media/MediaRoster.cpp?id=40de3cd148f2d8edbf4b60bd2221c43f267fea5a
but I can't see anything that might be the cause there.
Any insight appreciated.
Thanks,
-- Pete --
