asterisk users - Feb 2009 - asterisk 1.4.23.1 and mISDN 1.1.8 segfaults

hi all,

I'm have a bit of a hard time with some segfaults on running 1.4.23.1 and
mISDN 1.1.8. I already enabled " DONT_OPTIMIZE" and "
DEBUG_THREADS" in
asterisk so I can now generate a bt. I did that (following the instructions
on voip-info) but I'm not sure how to "read' the output now.

By looking  at the bt below, can one see if the problem is caused by
something special ? I'm running debian etc with kernel 2.6.18-6-686.

Core was generated by `asterisk -vvvvvvvvvvvvvg'.
Program terminated with signal 11, Segmentation fault.

Thanks in advance for any pointers.
