Comment (by 191919):
I have recloned ffmpeg source from `git://source.ffmpeg.org/ffmpeg` (I
guess SourceTree messed up the version number). The problem is still
reproducible.

The output of OS X's `sample` utility is identical as before.
Since Apple doesn't provide gcc as their compiler, I had to switch to the
clang's svn version.
{{{
~/ffmpeg$ /opt/bin/clang -v
clang version 3.4 (trunk 182231)
Target: x86_64-apple-darwin12.3.0

}}}
This time:

}}}
So the conclusion: it was a bug of Xcode compiler. I will commit a bug to
their bug tracker and will try to find which caused the problem.
Thank you all guys.
