[Speex-dev] Fixed point divide-by-zero issue for testdenoise.exe

[Ajay Dhanapalan]

Hello!



I tried quite a few things before I could reach out to the community. The
problem I am facing is that I am unable to run SPEEX in fixed point at WB
15ms or 20ms frameSize for some files. I tried using rc1.1/1.2/1.3 releases
and all exhibit the same issue.



I tried enabling the debug option during configuration step: ./configure
–enable-fixed-point-debug; but this gives bit exact outputs to floating
point. I am not sure if this is running fixed point.



Any help is greatly appreciated!



The stackdump is as follows:
