internal compiler error

[dj95]

When I try to crossbuild the 4.1.6 emlid kernel for the raspberry pi 2, the crosscompiler crashes with the following error.

lib/raid6/neon4.c: In function ‘raid6_neon4_gen_syndrome_real’:
lib/raid6/neon4.c:113:1: internal compiler error: in dwarf2out_frame_debug_adjust_cfa, at dwarf2cfi.c:1078
 }

After a short research I found the following launchpad bug(https://bugs.launchpad.net/ubuntu/+source/gcc-4.8/+bug/1429894), which mentions the exact same problem.

Which cross-compiler are you using? The newest in tools repo is:

arm-linux-gnueabihf-gcc --version
arm-linux-gnueabihf-gcc (crosstool-NG crosstool-ng-1.22.0-88-g8460611) 4.9.3

I use the gcc-linaro x64 crosscompiler, which is delivered in version:

arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03) 4.8.3 20140303 (prerelease)

Downloading the latest gcc from the linaro website solved the problem. The version of this crosscompiler is

arm-linux-gnueabihf-gcc (Linaro GCC 5.3-2016.02) 5.3.1 20160113

Okay, but this is the newest gcc from this repo: https://github.com/raspberrypi/tools/tree/master/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf I assume that doesn't have the error? (appeared to be a 4.8 error).
