FreeSwitch crashes upon mod_spandsp_fax

16 Apr 2015

      Hi,
I've just tried to load module spandsp_fax and freeswitch crashes with a
core dump saying:

[CRIT] mod_spandsp_fax.c:201 timer init failed.
Segmentation fault (core dumped)

If I don't load this module FS starts but prints this:

[CONSOLE] mod_local_stream.c:220 Can't start timer.

Following is the dump trace.

warning: no loadable sections found in added symbol-file system-supplied
DSO at 0x7fffc35fe000
Core was generated by `./freeswitch'.

Any pointers would be greatly appreciated.
