Thanks for the nice diagnosis. I tried another compiler as you suggested:
* "clang version 3.7.0 (trunk 239386)" produces faulty code
* Yosemite's default compiler "Apple LLVM version 6.1.0 (clang-602.0.53) (based
on LLVM 3.6.0svn)" works

In both cases, passing "-mstackrealign" in CFLAGS does not matter.

Should this be submitted to clang?
