[Bug tree-optimization/16688] New: [3.5 regression] ICE in group_aliases, at tree-ssa-alias.c:1234


This is a new ICE introduced between 2004-07-21 and 2004-07-22. I 
don't right now have the time to reduce the testcase, so it is pretty 
big, but maybe someone has some clue as to what is going wrong. 
 
deal.II/deal.II> c++ -O2 -c dof_renumbering.ii  
dof_renumbering.ii: In static member function `static void 
DoFRenumbering::downstream_dg(MGDoFHandler<dim>&, unsigned int, const 
Point<dim>&) [with int dim = 2]': 
dof_renumbering.ii:53217: internal compiler error: in group_aliases, at 
tree-ssa-alias.c:1234 
Please submit a full bug report, 
with preprocessed source if appropriate.
