> To run it, just extract it and run as root

> # chroot . /test.sh

> Using that one I get segmentation faults very quickly on 2 Arndale
> boards running 3.7 / 3.9 I can access right now, but not on a Chromebook

> Also, disabling ASLR did _not_ help in the end. It just some times

> Bug description:
> With Rony's current kernel and u-boot, my Arndale board segfaults when
> building GCC or benchmarks. Something like:
>
> /bin/sh: line 1: 22855 Segmentation fault (core dumped)
> build/genattrtab ../../../gcc-linaro-4.7-2012.11/gcc/config/arm/arm.md
> insn-conditions.md > tmp-attrtab.c
> make[7]: *** [s-attrtab] Error 139
>
> The board generally works but doesn't handle heavy loads.
>
> I'll try clocking it back down to 1.0 GHz from 1.4 Ghz and see if that
> helps. I added a small stick on heatsink which is currently at 62 deg
> C and will get hotter.
