For me, Firefox > works just fine on 13.0-CURRENT. Are you compiling world with any > special options, or with a non-default compiler? Thank you for reply. I was compiling without special options. % cd /usr/src (/usr/src -> nfsserver:/usr/altlocal/freebsd-current/src) % svn up % time sh -c 'make -j4 buildworld && make -j4 buildkernel' (nfs connection was stalled. So I rebooted machine and re-makeworld as follows) % su # reboot % cd /usr/src % time sh -c 'make -j4 buildworld && make -j4 buildkernel' % su # make installkernel # reboot # cd /usr/src # make installworld (Broked userland was installed.) # mergemaster -Ui # make check-old # make BATCH_DELETE_OLD_FILES=yes delete-old # make check-old-libs # make BATCH_DELETE_OLD_FILES=yes delete-old-libs # pkg upgrade # reboot (I can not make buildworld with the libunwind: decodeEHHdr error.) I did rebuild kernel and userland with another machine and reinstall kernel/userland to the broken machines. Now they are working well. P.S. Althougth I was applied patches of https://reviews.llvm.org/D57081, no libunwind: decodeEHHdr messages are displayed. I think D57081 is not cause of this. -- Masachika ISHIZUKA
