--- Comment #4 from Iain Sandoe <iains at gcc dot gnu.org> 2011-10-19 12:22:04 UTC --- (In reply to comment #3) > Could I have ssh access to one of the boxes that fail? unfortunately, I can't do that - company boxes here afflicted by company policy; Jack Howarth seems to be able to - I think he might have a PPC box still. Otherwise we can offer to try and answer specific questions; I've got other fails in struc-layout etc. that are bus errors in libcpp: e.g. Program received signal EXC_BAD_ACCESS, Could not access memory.
