[Asterisk-Users] fax/sandsp segfaulting asterisk

[Dan Cunningham]

Like some others on the list spandsp is segfaulting asterisk when recieving
a fax.   I'm on debian testing/unstable with freshly checked out asterisk
CVS and sandsp. My libtiff version is 3.6.1. 

Here is the GDB output

I can't get it to run right in valgrind, my box is to slow (fax times out)
and sometime valgrind just locks up.

Any ideas?
Thanks
