--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> 2011-09-16 09:48:11 UTC --- Now it dies at /abuild/jh/trunk-install/lib/gcc/x86_64-unknown-linux-gnu/4.7.0/../../../../x86_64-unknown-linux-gnu/bin/ld: warning: hidden symbol 'typeinfo for SolarMutexResettableGuard' in /abuild/jh/libreoffice/core/workdir/unxlngx6.pro/CxxObject/sfx2/source/appl/app.o is referenced by DSO /abuild/jh/libreoffice/core/solver/unxlngx6.pro/lib/libvcllo.so lto1: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. lto-wrapper: /abuild/jh/trunk-install/bin/g++ returned 1 exit status I saw previously segfault in ipa-cp, so this might be same issue. Honza
