Hello Jeff! Congratulations on 2.95 being out and thanks for the
response (I'm guessing the close timing of those events is not a
coincidence :-)).
I did look at the .lreg and .greg dumps and the problem was in global
register allocation (at least in the sense that I was able to fix it
in global.c in a vaguely clean-seeming way). I came up with a patch
which I sent to egcs-patches (I currently plan to ship this patch with
Red Hat but I'd be very eager if anyone can offer a critique as I
don't really know whether I fixed it in the right way).
My patch is at
