[asterisk-dev] Debuging a channel driver

[luciano digivoice]

Hello everyone,

I'm trying to debug my channel driver. I already enabled DEBUG_THREADS and
DONT_OPTIMIZE Asterisk parameters, I have a thread and this one is
genarating a core dump (I think), using gdb application I only can see this:

Core was generated by `asterisk -cvvvg'.
Program terminated with signal 11, Segmentation fault.
#0  0xb7ec818a in strcmp () from /lib/libc.so.6
(gdb) bt
#0  0xb7ec818a in strcmp () from /lib/libc.so.6

context=0x240 <Address 0x240 out of bounds>,
    exten=0xad5522d8 "", priority=1, label=0x0, callerid=0x8297568 "",
action=E_MATCHMORE) at pbx.c:979

#6  0xb80341b5 in start_thread () from /lib/libpthread.so.0
#7  0xb7f2638e in clone () from /lib/libc.so.6
(gdb)

But "#4  0xb5706344 in ?? () from /usr/lib/asterisk/modules/chan_dgv.so"
don't help me to see the problem.

What I need to enable or do to debug my threads.

Thanks a lot.
