Unfortunately, but 8603 seems to cause internal compiler errors on select files
when using -O3. -O{s,0,1,2} are unaffected.
I'm attaching pp.i (preprocessed pp.c from libperl), and flist.i (preprocessed
flist.c from rsync) as test cases.
gcc-4.3.4 does not exhibit this failure, but when patched from bug 8603, it
fails. gcc-4.4.1 does not exhibit this failure, but gcc-4.4.2, which includes
the patch from 8603, does fail.

Both files compile OK with 4.5 cross from x86_64-pc-linux-gnu.
Probably a target specific patch should be backported from mainline to 4.3 and
4.4 branches.

This reduced testcase fails also on 4.5:
--cut here--
int make_file (int a, int b)
{
int foo = a * sizeof (int);
if (b)
foo += sizeof (int);
return foo;
}

WRT the test suite: should it be
/* { dg-options "-O2" } */
or
/* { dg-options "-O3" } */
That is, -O2 or -O3? I could only produce the internal compiler error with -O3,
and not at all with -Os, -O0, -O1, -O2.

The testcase also fails with -O2,.
