I sent this right before the holiday and thought I'd sent out a reminder
today. This is http://gcc.gnu.org/ml/gcc/2004-09/msg00184.html
My investigation showed that it was a /u call_insn at the abort point, but
I don't understand the code enough to know why that just started happening.
-----------------------------------------------------------------------------
This appeared with something checked in sometime Friday.
I verified that it was *not* the change to lcm.c that caused it. I'll
investigate further, but does anybody have any ideas?
