[Speex-dev] AEC init crashes

[Anton A. Shpakovsky]

Hello again,

Could it possibly happen due to SSE optimization or floating point
operations?

The only bottleneck I've found out is DIV32_16 define. 

But what can be wrong with float/float on the only WIN32 XP machine?

 

Regards,

Sorry, I've forgot to mention init params:

Frame_size is 441 samples and filter_length is 4096.

..don't think it makes any sense though..

Hello,

 

I've just caught a strange crash in speex_echo_state_init routine. It
happened only on one WinXP machine, while on others using XP, Vista and
7 everything is fine. 

Crash occures in mdf.c line 434: st->spec_average =
DIV32_16(SHL32(EXTEND32(st->frame_size), 15), st->sampling_rate);

 

Got any ideas or should I provide more information of the OS?

Thanks a lot!

 

Regards,

Anton A. Shpakovsky
