Ok, simpler test case. Add reverb (concert hall sound effect) to
track and it crashes occasionally when played.
Heres the error:
cinelerra: pthread_mutex_lock.c:80: __pthread_mutex_lock: Assertion
`mutex->__data.__owner == 0' failed.
Aborted (core dumped)
The backtrace on the core file says this:
(gdb) bt

#9 0xb740ab7e in clone () from /lib/libc.so.6
Line 501 of reverb.C is this:
input_lock.lock();
I guess I need to read up on pthread locking.
Anyway, can anyone help out here? Does this crash happen for other people?
Should I file another bug for this?
I'd like to help out and start understanding what's going on and
solving some of the crashes that I run into. But I'm at a loss right
now.

Here's backtrace info from the core dump:
(gdb) bt
#0 0xffffe410 in __kernel_vsyscall ()
#1 0xb7395129 in raise () from /lib/libc.so.6
#2 0xb7396553 in abort () from /lib/libc.so.6

#7 0xb74ad167 in start_thread () from /lib/libpthread.so.0
#8 0xb7423b7e in clone () from /lib/libc.so.6
Line 505 looks like this (in reverb.C):
for(i = 0; i < plugin->total_in_buffers; i++)
I'm not familiar with the flow of the code but, I can only find one place where
total_in_buffers is set on the plugin.
If anyone can shed some light on how to fix this I'd be very happy.
thanks
