Spandsp, rxfax and segfault

I’m having problems, and I am sad.

spandsp-0.0.4pre9
libtiff-3.7.3
asterisk-1.4.11
rx/txfax from the only place i can find them (soft-switch.org/downloads/sn … erisk-1.4/)

Compiled, patched, installed without a glitch. Hurray.

Dialplan…
.
.
exten => fax,1,rxfax(/tmp/fax.tiff|debug);
.
.

Call comes in, faxdetect detects it very well, sends it to my extension fax conversation begins (rxfax kicks in, hurrah!). Then disaster…

Anybody else have this ? Anybody get this to work and with which libraries ? I’ve tried spandsp 0.0.3, and the latest from snapshot with pretty much the same results.
