[FFmpeg-devel] Strange issue debugging AAC

Hey all,

I'm running into a weird issue with get_bits() in the aac decoder that
I was hoping some one could help me with so that I can continue
hunting down bugs.

Consider the attached patch:

and the test stream at
http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_IEC_14496-4_2004_Conformance_Testing/audio_conformance/mpeg4audio-conformance/compressedMp4/al07_44.mp4

I'm getting different results from the #if and #else sections of the
code, and it's boggling my mind. Any assistance would be greatly
appreciated. I've tried both gcc-3.4 and gcc-4.3.

[Yes I am aware that the seem desyncs later on, that was the original
issue I was troubleshooting]

Thanks,
Alex Converse
