I have submitted bugzilla 215350: devel/powerpc64-gcc -r428604: The 6.2.0 based gcc (indirectly?) gets SIGSEGV building src/sys/modules/agp/agp_if.o but ctfconvert involved
Attempting to build src/sys/modules/agp/agp_if.o ets a SIGSEGV reported. Despite "segmentation fault" being reported for a powerpc64-gcc command the only .core file was for ctfconvert instead. ctfconvert does report its own death as well --but multiple times yet with only one core file present. With clang 3.9.0 issues and this there seem to be no modern toolchain for head for which I can do both buildworld and buildkernel and end up with a bootable PowerMac G5 powerpc64 system. For powerpc64 things have definitely regressed overall despite clang progressing some from where it was for 3.8.0 . Note: The problem was a test without forcing older devel/*-binutils or other such. I've yet to try such a mix-and-match involving xtoolchain.
