--- Comment #10 from David Abdurachmanov <david.abdurachmanov at gmail dot com> --- I did a quick test (still took several hours) with #1 and #3 patches and both seem to solve the issue. Patches were tested on top of r235408. Just in case I will run patch #3 (for now) again, but will force the whole world to be recompiled starting GCC. That is a more extensive, but also expensive test.
