[Bug tree-optimization/18611] New: ICE: in bitmap_ior, at bitmap.c:704 with -O1 -fmove-loop-invariants

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

With the snapshot 20041121 I get an ICE bitmap_ior, at bitmap.c:704
if I use the options -O1 (or higher) and -fmove-loop-invariants
Snapshot 20041121 has the same problem.
