[x264-devel] crash with x264 64bit on mac os x 10.5.8

[vmrsss]

Hello everybody. 

Running x264 64bit (compiled with llvm-gcc-4.2) on mac os x 10.5.8

> > x264 --version
> x264 0.80.1376+56 47740e0
> built on Jan  3 2010, gcc: 4.2.1 (Based on Apple Inc. build 5555) (LLVM build 2064.3)

with these parameters:

> x264 stream.y4m --threads auto --crf 22 --bframes 4 --b-adapt 2 --b-pyramid normal --direct auto --weightb --ref 6 --mixed-refs --subme 9 --me umh --trellis 2 --sar 64:45 --level 31 --output file.264

I systematically get the crash reported below in cpu_capabilities.h (the same code compiled at 32bit on the same architecture by the same compile runs that command just fine, albeit slow).

Does anybody know what's going on?

Thanks.
