[asterisk-users] spandsp 0.0.3 RxFax fax reception crashes bristuffed asterisk 1.2.13

[Marcel van der Boom]

Hi,

I'm using spandsp-0.0.3
[http://www.soft-switch.org/downloads/snapshots/spandsp/ 
spandsp-20061116.tar.gz]

on a bristuffed asterisk (1.2.13)
[http://212.91.251.199/~junghanns.net/downloads/bristuff-0.3.0- 
PRE-1v.tar.gz]

libtiff is at version 3.6.0

Running on: Linux router2 2.6.17-2-686 #1 SMP Wed Sep 13 16:34:10 UTC  
2006 i686 GNU/Linux
Debian testing distro.

I've tried many combinations of bristuffed ast and spandsp versions,  
but all fail at the same point. The last combination i got to work  
was bristuffed 0.3.0-PRE-1i with spandsp-0.0.2-pre25 (on an earlier  
kernel)

The app_rxfax.c in use is from:
[http://www.soft-switch.org/downloads/snapshots/spandsp/test-apps- 
asterisk-1.2/app_rxfax.c]

On reception of a fax through RxFax, i get the exception. The  
relevant part of the dialplan is

[macro-faxreceive]
; Receive a fax
exten => s,1,Set(FAXFILE=${FAXSPOOL}/${UNIQUEID}.tif)   ; Save the  
fax in a tif file
exten => s,2,RxFAX(${FAXFILE})                          ; Receive it
exten => s,3,NoOp("Fax reception complete")             ;
exten => s,4,Hangup

Running asterisk (with the above versions) through gdb and doing a  
backtrace gives me:

This seems to indicate that the ast_frfree(inf); at line 327 of  
app_rxfax.c causes the problem chain?

I'm a bit lost on how to debug this further. Is this actually a  
spandsp problem or is another package the cause?
Any tips?
