[asterisk-users] Asterisk 1.4.11, res_features.so, SegFault

Tue Sep 11 02:22:50 CDT 2007

Hi All,

I have a really strange issue occuring where if I run "show dialplan" or
"dialplan show" or "dialplan show parkedcalls", then asterisk dumps core.

It only appears to happen with contexts that are created within
res_features. I am able to display all my other dialplans, but, every
time I try to just do a normal "dialplan show" asterisk core dumps
(Segmentation Fault).

My environment is as follows:

Asterisk v 1.4.11
Solaris 10 update 3 (11/06), patched current
gcc v3.4.3

example console output
