Removing -g from various CFLAGS, as proposed in PR 6669, doesn't change the outcome, while removing -O2 (PR 6552) makes it even worse, as some of the little helper utilities that get built along the way (gentype, genmode, and friends) produce a bus error when executed. > Andrew's explanation certainly sounds plausible.

Tried that, too. No betterment. And I only have IRIX 6.2 at my disposal. I have, meanwhile, upgraded to GCC 3.4.3, but it didn't make a difference. Out of sheer desparation, I have adopted a brute- force method to get rid of the symptoms (not the problems, though!). See the transcript below. I have finally been able to produce a GCC 3.4.3 but I am all too aware of the fact that it is a botched one. Not surprisingly, it could not be used to bootstrap itself. Any ideas are appreciated.
