I did, but it brought no alleviation. 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.

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.
Regards,
Frank
