[speex-dev] Coredumps when --enable-sse is selected

[Malcolm Baldridge]

System: Linux 2.4.25, glibc-2.3.2, 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
1.1.4), and the result is the same.

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

Backtrace:

My build line is as follows:

CFLAGS='-O -g -march=pentium4 -mcpu=pentium4' CXXFLAGS='-O -g
-march=pentium4 -mcpu=pentium4' ./configure --enable-sse --enable-epic-48k
--prefix=/usr/local

Command line which triggers the coredump:

$ speexenc --dtx --vbr -w test.wav test.spx   
Encoding 16000 Hz audio using wideband (sub-band CELP) mode (mono)
