--- Comment #8 from Aaro Koskinen <aaro.koskinen at iki dot fi> ---
ICE backtrace seems to be same as in Bug 61430. The fix for that has not been
backported to 4.9 branch. I tested it and it seems to fix the issue at hand.

The fix: https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=211701

This patch should probably be backported as it is not currently possible to
compile GCC 4.9.2 release on ARM (or maybe some newer ARM archs work).
