I can confirm that the bug still exists in glibc 2.24 and HEAD from glibc git.  Also it appears that the issue on the llvm mailing list was just dropped without any resolution:

r255371 - Error on redeclaring with a conflicting asm label <http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20160104/146075.html>

As far as your review of the patch by weimingz, that is beyond my skill level so I will let him reply.  Thanks!
