This broke regressions on a lot of configurations (not sure why it 
didn't break them all):

   http://fate.multimedia.cx/

Here is the first failure point for x86_32/GCC 4.3.1 as well as 
x86_64/gcc-SVN:

./ffmpeg_g -y -flags +bitexact -dct fastint -idct simple -ab 128k -ac 2 
-f s16le -i tests/asynth1.sw -sample_fmt flt -acodec pcm_f32be 
./tests/data/a-pcm_f32be.au

It segfaults. This is the backtrace from the x86_64 configuration:

Program received signal SIGSEGV, Segmentation fault.
