[asterisk-dev] Segfault Asterisk 1.2.31.1 on Debian Lenny AMD64

[Stefan Schmidt]

Hello,

I´ve a Problem with an asterisk system running on Debian Lenny (5.0)
with a sangoma A108d Octo E1 Card (wanpip-3.3.15 driver), Libpri 1.2.8
and zaptel-1.2.27

Sometimes the asterisk exits with an segfault and in the core dumps i
cant see why. Because everytime it happens with another modul used.

Here are 3 core dumps of the segfault:

XXX replaces customer details like callnr.

we are about to update to version 1.4 but we want to know if this
segfault could happen on 1.4 too cause its the 64bit lenny system or the
sangoma 64bit driver.
