I'm suspecting the code was compiled with CPU specific extensions which the current one does not support. Try recompiling FreeSWITCH without the SMID extensions for mod_spandsp and see if that helps.

Hi,

I have an odd issue. I was going to run out of the box FreeSWITCH on a windows server and just by double clicking on freeswitch.exe I get a crash. When I did a debug I found it was illegal instruction error.

If I remove mod_spandsp The program starts up fine. I then try to do a tone detection and then the program crashes again. What would cause the same release code to work on one server but crash on another server?
