Yes, that's right. speex_bits_insert_terminator keeps calling
speex_pack_bits forever, because bitPtr never reaches 15. Eventually the
bit buffer runs out of room.

I'm sure you'll still get a low MIPS count after we find the fix to
fixed_generic.h.

Good, that explains other problems I've seen.

Speex on TI C6x, Problem with TI C5x Patch
Hi Jean-Marc, Hi Jim,
I have also seen some problems with the 1.1.8 release on the C55x. So far I
have boiled down the issues to the following:
1) We need our own "fixed_xx.h" header file. I don't know why, and haven't
had time to investigate, but there is a definite improvement when I use the
attached fixed_c55x.h file which has turned all the maths into inline
functions.
