I have a patch, I still have to check complex, I think it is ok because we have
expanded the division by the time we ran LIM.

Mine, this is a regression as 4.0.1 did not ICE.

------- Comment #5 from pinskia at gcc dot gnu dot org 2008-09-28 21:58 -------
On the trunk we get a slightly different ICE:
t.c: In function 'RRB':
t.c:4: internal compiler error: in gimple_assign_set_rhs1, at gimple.h:1755
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
But that is because we catch the error earlier rather than during verification.
