There is an issue with > rtld's use of SSE on amd64 which will be fixed soon. i've seen this issue, too. i did a complete buildworld/installword using gcc as compiler and after that everything worked fine again. so clang seems to be causing the problem. simply back out any clang entries in src.conf and buildworld/installworld should fix your issue. please also see the thread "issue with clang and CPUTYPE native" on freebsd-toolchain, which seems to also be caused by the rtld issue. cheers. alex > > -- > Alexander Kabaev -- a13x
