Hi Oleg,

Thanks for the bug report and the fact you spent the time to track down
where it broke.

by exit, you mean segfault (or whatever the Windows equivalent is), a
division by zero, or something else? Do you have the line number by any
chance? Also, if you have a file that can reproduce the problem with
speexdec (I assumer it's the decoder that crashes), that would help a lot.

Sounds like you have VAD/VBR enabled, is that correct? I'll have a
closer look at that change in the mean time.
