Confirmed the 4.4 ICE.  -O2 -ftracer -fsched2-use-superblocks -fpic -m32.
Cannot reproduce on 4.5.

Slightly more reduced testcase:
extern __SIZE_TYPE__ strlen (const char *);
extern int f1 (void *);
extern char *f2 (void);
extern void f3 (int, int);
static char *a;
char *b, *c, *d, *e;

void
foo (void)

  f = (a ? strlen (a) : strlen ("abcde"));
  f += (b ? strlen (b) : 0);
  f += (c ? strlen (c) : 0);
  f += (d ? strlen (d) : 0);
  f += (e ? strlen (e) : 0);
  h = f1 (strlen);
  g = strlen (a);
  f3 (g, f);
}

void
bar (void)
{

> This patch works for me.

Does it work for testcase from #1 as well?

I was bisecting trunk to find where this is fixed, it seems to be somewhere
between r151400 (20090904) and r151500 (20090908).

However, I was testing against original testcase from #1, with crash in:
xkbInit.c: In function 'XkbWriteRulesProp':
xkbInit.c:231:1: internal compiler error: Segmentation fault

Of course the fact gcc-4.5.0-alpha20090904 crashes with the same error message
can be just a coincidence.

The patch 149082 contains two parts: 1. fixed a wrong optimization in
tree-ssa-sink.c, it affects performance only. 2. fixed a i386 back end bug in
i386.c.

I've tried the bug fixing code in i386.c, unfortunately it doesn't work. So it
looks more like the better optimization in the patch hides an unknown bug.

gcc44-pr41762.patch

Patch I'm going to bootstrap/regtest.
As ix86 backend doesn't know what kind of VALUE preserving mode the pass it
occurs in uses, it needs to be prepared even for VALUEs discarded as useless by
remove_useless_values, similarly e.g. to get_addr in alias.c which also checks
for them.

I am receiving the same error in r151451, disappears in r151453 (20090905)
(trunk).
gcc 4.4 branch (r153538, 20091025) still has this problem, but needs adding of
-freorder-blocks-and-partition

This error appears only with testcase from #1, testcase #2 crashes only in 4.4
branch.
Testcase #4 crashes also only in 4.4 branch, but without
-freorder-blocks-and-partition
