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
 Thread model: posix
 }}}

 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.
