With yesterday's CVS I get this ICE:
spec/src> c++ -O3 -c tria.ii
tria.cc: In member function `typename
TriaDimensionInfo<dim>::active_quad_iterator
Triangulation<dim>::last_active_quad(unsigned int) const [with int dim = 3]':
tria.cc:3876: internal compiler error: in get_indirect_ref_operands, at
tree-ssa-operands.c:1370
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Unreduced sources. I won't have time to reduce them for a while, so if
someone wants to beat me to it, I'd be happy.

Good job, Daniel! From your testcase, we get on a straight line to this one:
------------------
struct Base {
int state ();
int i;
};
struct Derived : Base {
Derived & foo () {
while (state() == 0)
return *this;
return *this;
}
};
void bar () {
if (Derived().foo().state() != 1)
return;
}
------------------------
g/x> /home/bangerth/bin/gcc-4.0-pre/bin/c++ -c x.ii -O3
x.ii: In function `void bar()':
x.ii:14: internal compiler error: in get_indirect_ref_operands, at
tree-ssa-operands.c:1370

And one can reduce it further to the testcase in PR 17273.
