Bug#799872: gcc-5-arm-linux-gnueabihf: when compiling Linux Kernel's rcutiny.h, GCC-5 segfaults
Package: gcc-5-arm-linux-gnueabihf
Version: 5.2.1-16cross1
Severity: grave
Justification: causes non-serious data loss
Dear Maintainer,
In order to reproduce the problem, I have a .config which I tried to
build my v4.3-rc1-based kernel tree. I'm cross-compiling kernel with
ARMHF GCC-5 and this specific defconfig, but when trying to compile
rcutiny.h, GCC segfaults with error below:

from kernel/rcu/rcutorture.c:28:

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.
