Summary:                    [patch] Regular segfault with chan_unistim
Description: 
Running Asterisk 1.6.0.8 on Ubuntu 8.10 Server. This same crash also
happens on 1.2.26 and 1.4.2x with the chan_unistim drivers. We have approx.
40 unistim handsets, in a callcenter environment. At least once a day,
Asterisk segfaults with the same gdb output.

It appears to happen during attended transfers, using the res_features
atxfer.

gdb output below.
