Arnout Vandecappelle <arnout at mind dot be> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |arnout at mind dot be --- Comment #4 from Arnout Vandecappelle <arnout at mind dot be> --- This bug was already reported before at glibc: https://sourceware.org/bugzilla/show_bug.cgi?id=29621 There it was concluded that it is due to gcc stage1 being built with CFLAGS_FOR_TARGET="-O0". This is not something that is tested in glibc's testing infrastructure. It's not clear to me whether the issue needs to be solved in GCC or in glibc.
