I don't see it at all with gcc 4.8, 4.9 and trunk on darwin14. Probably was a
bug in dsymutil (most likely)…

Doesn't happen for me with the 4.5 branch. (I don't have a current trunk
compiler to compare with.)

it still fails for me on ppc and i686 4.6.0 r159518 and 159528 resp.

comparison between asm files without an with -feliminate-dwarf2-dups

the main difference seems to be moving the filename from the debug abbrev.
section to the debug string section.
