Speex dev - Sep 2009 - SPEEX_PREPROCESS_SET_ECHO_STATE produces heap corruption

Hi,

when I use preprocessor with AEC, VC++ alerts me about heap corruption.

I have protected speex_echo_playback, speex_echo_capture and 
speex_preprocess_run with mutexes, to avoid echo_state being used at the 
same time, but it still happens.

Any help about this ussue?

Thank you.

Now I see that it happens when I specify a framesize in 
speex_echo_state_init greater than the one used in 
speex_preprocess_state_init.

Next combination works:
codec framesize = 160
preprocessor framesize = 160
eco framesize = 160


Next combination DOESNT work (produces heap corruption):
codec framesize = 160
preprocessor framesize = 160
eco framesize = 1600


Is it possible to use these values?

Thank you.
