--- Comment #2 from Maxim Kuvyrkov <mkuvyrkov at gcc dot gnu.org> ---
>From further analysis it seems this problem was due to how old armv7 kernels
(3.10) allocated process stack. The stack bumped against special
kernel-provided page, so, when compiler generate bigger-than-usual stack
frames, the stack would overflow and process would crash.
Non-ancient kernels don't have this problem.
