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.

Unfortunately, rather than a crash, this time the log filled (up to 2Gb
limit) with:

 ERROR[30968] channel.c: ast_read() called with no recorded file
descriptor.

See the attached unistim.log file.
