--- Comment #8 from Laurent Aflonsi <laurent.alfonsi at st dot com> --- Jeffrey, As you asked for, I have performed much more testing on that fix. I am far from having done as many tests as Jakub in 2004. In particular, I have not been able to test on ppc/iaxx, because i don't have any available. I have performed a profiledbootstrap in a loop all over the weekend on my x86_64 with parallelized builds (-j 4, -j 5, ... -j 12). which represents 80 builds using various parallel schedules. All of them have finished successfully. I have not observed any instabilities. It has been also regtested gcc/g+/libstdc++, 7 times in a row without any failure. Thanks Laurent
