Thanks for all the posts.
It's an Intel processor. I tried recompiling multiple times, but did not try cleaning the source tree, or
re-uncompressing the tar.
Should I run make clean, or make mrproper after deleting the directory, and
uncompressing the tar?

An ICE (internal compiler error) means something *apparently* went

Ken,
Do you have any knowledge about how the newer AMD processors
(Phenom II, A10, etc.) hold up in this regard?
My phenom is actually AMD Phenom(tm) II X4 965 Processor
I know of one person, who sometimes posts on lkml, who also has a
similar processor and now never goes beyond make -j4.
My own A4, when it was alive, showed no problems (apart from only
having two cores). My A10 (kaveri) is fine, and there I use make
-j5 because it has an SSD. So, from my experience only the Phenom
is a problem.
OTOH, in many things they are slower than my SandyBridge i3, and in
particular an SBU (single threaded) is much slower - some of that,
but not all, might be because the acpi cpufreq governor works less
well on AMD CPUs than the old K10 code did.
As to the problem of the OP, is it possible that gcc was not complied
for the correct target such that in unusual circumstances it really
will attempt to execute an unsupported CPU instruction?
If a reattempt is made to build atk (after cleaning the source tree)
does the exact same error occur at the same place? If so, a hardware
problem is less likely.
Yes, those both sound sensible.
Another possibility is some kind of stack corruption (caused by
a bug in gcc or one of the libraries it depends on) where data
is somehow overwriting exec code.
For that, I hope not ;-) That does sound suspiciously like what the
phenom appears to do on its bad days. But we don't know what CPU the
OP was using.
