>Description:
While running exult on -current NetBSD/i386 (or NetBSD/amd64), i'm seeing many
pthread assertions failures :


njoly@cixy [~/Ultima7Vf]> exult 
Exult version 1.2
Built at: Jan  9 2005 15:21:09
Compile-time options: USE_EXULTSTUDIO, HAVE_ZIP_SUPPORT
Compiler: gcc, version: 3.3.3 (NetBSD nb3 20040520)


Platform: Unknown
Exult path settings:
Data          : /usr/pkg/share/exult
Digital music : /usr/pkg/share/exult/music


Music player: Internal cheapass forked midi player
Black Gate   : found
exult_bg.flx : found
Serpent Isle : not found (static/sispeech.spc)
exult_si.flx : found
Starting forked player failed
assertion "unreachable" failed: file "/local/src/NetBSD/src/lib/libpthread/pthread.c", line 523, function "pthread__idle"
[...]


Then, the system becomes unresponsive until the `exult.core' file is
generated (about 770MB).


I tracked down this problem, and noticed that exult program depend on a
missing `playmidi' command to play MIDI files :
http://sourceforge.net/projects/playmidi/
But i failed to make it work on NetBSD.


As a workaround for NetBSD, i patched `audio/midi_drivers/forked_player.cc'
to use native command `midiplay' instead.


For the pthread assertion failure, i can't figure if the problem comes from
exult code, or if our pthread library is faulty ... I'm not familiar enough
with pthreads.
