i think this is the same as 66146, i'll add an update comment there.

PR66146 is non-x86, whereas this fails on x86 too. It's possibly related though.

Comment 3 Jonathan Wakely 2016-03-18 15:35:32 UTC

Or more accurately, non-(x86-*-gnu), since x86 with musl libc has the same problem as non-x86 glibc.
