speex and thread question.
...every thing
is going fine.
So I would like to know if there are some special things I have to worry
about when I'm using speex and threads.
Thanks In advance.
Here a backtrace of gdb :

Coredumps when --enable-sse is selected
...3.2, gcc-3.2.3 (weird palindrome there), on a
Williamette core Pentium 4 (1.6Ghz) system.
I've tried both speex 1.1.5 release, and the current CVS (which self-IDs as

I suspect some funk in the use of the SSE intrinsics macros.
