[Bug tree-optimization/23433] New: ICE: tree check: expected real_cst, have integer_cst in const_binop, at fold-const.c:1512

["micis at gmx dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When I compile qt334 with the actual snapshot of gcc41 (20050813) I get an ICE 
with -O3 -funsafe-math-optimizations. This ICE is new, the snapshot from last 
week is working.
