i think we'd rather wait for upstream gcc to land something and then we'll cherry pick that back

The closest upstream bug is http://gcc.gnu.org/PR58962.  I haven't seen any patches posted.

Comment 4 Chris Mayo 2014-10-31 19:31:33 UTC

Fix committed upstream:

should be fixed w/gcc-4.8.[45] and gcc-4.9.[23] and >=gcc-5

don't see much point in backporting past that
