--- Comment #95 from Dzianis Kahanovich <mahatma at eu dot by> --- Just FYI. Novadays, on my Thinkpad tablet with Atom (32 bit userspace Gentoo), I globally replace patch/-mstackrealign to "-fvect-cost-model=cheap -fsimd-cost-model=cheap -malign-data=cacheline" and all works fine for -O3 +. (This is dirty example, as cacheline for some old SSE CPUs are different, etc).
