ICEs for me with 4.4.5 but works on the trunk.

Here is a reduced testcase:
struct vector
{
char *_M_start;
char *_M_finish;
};
struct LoopBase
{
static LoopBase *f();
LoopBase *ParentLoop;
vector SubLoops;
~LoopBase()
{
for (int i = 0, e = SubLoops._M_finish - SubLoops._M_start; i != e; ++i)
delete f();
}
};
void deleteLoopFromQueue(LoopBase *L, int b)
{
if (L->ParentLoop)
while (L->SubLoops._M_start != L->SubLoops._M_finish)return;
else
while (L->SubLoops._M_start != L->SubLoops._M_finish)return;
delete L;
}
--- CUT ---
The delete loop is actually an empty loop but the tree level does not see that
for some reason:
# prephitmp.36_112 = PHI <prephitmp.36_6(4), prephitmp.36_3(3)>
# prephitmp.36_21 = PHI <prephitmp.36_6(4), prephitmp.36_3(3)>
D.2385_15 = (long int) prephitmp.36_21;
D.2387_17 = (long int) prephitmp.36_112;
Those PHIs are the same.
