--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Bootstrap is fine if one uses older binutils. The thing is that cxx11-ios_failure* is built by hand first with -g -O2 -S, then the assembly is modified by a script and then it is assembled, and as older assemblers would fail miserably on assembling .s file containing .debug_info etc. with -g (-gdwarf-2 passed to assembler), the assembly is invoked with -g -O2 -c -g0. I really think this should be fixed solely on the assembler side, and if needed, we can add a temporary workaround, I guess compiling cxx11-ios_failure* with -gno-as-loc-support could fix that.
