[Asterisk-Users] fax/sandsp segfaulting asterisk

[Dan Cunningham]

I downgraded to 3.5.7 and that seemed to work, for others with this issue I
just manually downloaded these packages from debian/testing and downgraded
with dpkg -i libtiff*.pkg , this worked with no dependency problems.

Sorry I  had assumed my libtiff would be fine (deb/unstable) but after
reading the list more carefully 3.6.1 seems to be broken, is 3.5.7 OK
(deb/testing)?

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
