[Bug middle-end/22398] New: ICE in compare_values, at tree-vrp.c:445

["dank at kegel dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling arch/sparc/kernel/process.c from linux-2.6.11.3
with gcc-4.1-20050709 fails with

arch/sparc/kernel/process.c: In function '__show_backtrace':
arch/sparc/kernel/process.c:204: internal compiler error: in compare_values, at
tree-vrp.c:445

Here's the command I use to reproduce:

sparc-unknown-linux-gnu-gcc \
-fno-strict-aliasing -fno-common -ffreestanding \
-O2     -fomit-frame-pointer -m32 -mno-fpu -fcall-used-g5 \
-fcall-used-g7 -c process.i

I haven't reduced process.i; it's 250KB.  You can download it
from http://kegel.com/gcc/process.i.txt
