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'.
