--- Comment #7 from Bernd Schmidt <bernds at gcc dot gnu.org> 2011-10-17 11:40:25 UTC --- AFAIK there's no IRIX6.5 machine in the compile farm. Can you debug a bit at the point of the crash to see what's going on? Configure won't let me build the target without "--neable-obsolete" anyway, so is it a serious issue?
