This ICE was fixed here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33256
Unfortunately the fix is GPLv3-licensed, so we can't merge it
back as-is.

I tracked down the cause of the issue to
contrib/jemalloc/include/jemalloc/internal/jemalloc_internal.h line 214.
So possible workaround could be replacing this line to
#if defined(JEMALLOC_DEBUG) || defined(__mips__)

Ugly, yes, but good enough as a band-aid until we figure out what to do
with the real issue
