I just tried to compile the Suse Linux package
fontconfig-2.4.2-83 with the GNU C compiler
version 4.4 snapshot 20080502
The compiler said
fccharset.c:1174: internal compiler error: in compare_values_warnv, at
tree-vrp.c:892
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flag -O3 required.

Created an attachment (id=15614)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=15614&action=view)
somehwat reduced testcase
It's probably PPRE that messes up (-O3 -fno-tree-pre is fine, -O2
-finline-functions as well).

Better reduced testcase:
typedef unsigned long int uintptr_t;
typedef struct _FcCharLeaf { } FcCharLeaf;
struct _FcCharLeafEnt {
unsigned int hash;
int leaf;
};
struct _FcCharSetFreezer
{
int orig_hash_table[67];
};
struct _FcCharLeafEnt *ent;
int a, f(FcCharLeaf * );
void FcCharSetFreeze (struct _FcCharSetFreezer *freezer, int *fcs)
{
int i;
for (i = 0; i < *fcs; i++)
{
FcCharLeaf *leaf = (FcCharLeaf *)fcs;
unsigned int hash = f (leaf);
if (ent->hash == hash)
a = ent->leaf;
if (!a)
return;
}
freezer->orig_hash_table[((uintptr_t) fcs) & 67] = 0;
}
PRE is creating the mismatched PHI nodes.

PA_IN/OUT computes different for s/(unsigned long)/(long)/ in the following
testcase (long works):
int f(float * );
unsigned long FcCharSetFreeze (int *fcs, int b)
{
int i;
int a = 0;
