[Asterisk-Dev] whee, floating point exception with app_rxfax

[Steve Underwood]

Hi Anderw,

It has failed in process_baud, but that is a fairly big routine doing a 
lot of floating point. V.27ter is the slow modem, used for the 2400 and 
4800bps FAX modes. That is not used that much, so it has received less 
user testing than the V.29 code. It has been tested just as thoroughly 
here, though, and I never had a failure. Is this failure repeatable? If 
so, you need to build the code with the -g option to GCC, so it will 
tell you the actual source code line at which the error occured.

BTW: 261 FAXes is nothing. Some people have told me they put huge 
volumes through this software. :-)

Regards,
Steve
