--- Comment #18 from Jeffrey A. Law <law at gcc dot gnu.org> --- And I'll repeat what I said earlier. Someone is going to have to put this under a debugger and understand what's really going on. As far as I can tell that's never been done and while debugging via "i did this and it failed" can work, it's not terrible efficient. So again, I would suggest someone with an interest start by putting the failing stage2 compiler under the debugger to understand why the fault is triggering. That will also provide a bit more insight into what routine is most likely problematical.
