Summary:                    Memory segmentation fault on T.38 pass through
Description: 
I tried to use the chan_sip with T.38 pass through. An Fax is coming via
T.38 from
the Carrier an should go to a Linksys SPA2102 (T.38 enabled).
Short after starting UDPL traffic I got a segmentation fault.
The crash is 100% reproducible.
Outbound T.38 is no problem at all.

Okay, you can stop posting valgrind output for the time being.  Please
patch your system with the uploaded patch, and reproduce the crash, if
possible.  If it doesn't crash, please upload the 5 minutes from the logs
when you attempted to get it to crash and it didn't.  If it does crash,
please run gdb and get the output of the command "p last_function".

Due to the stack corruption, all other gdb and valgrind output are
useless, at this point.
