[Bug tree-optimization/23625] New: ICE: in bsi_after_labels, at tree-flow-inline.h:758

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

When I compile qt334 with the actual snapshot (20050826) of gcc41 I get an ICE
when I use -O2 -ftree-loop-linear -ftree-vectorize.

last working snapshot is:   gcc-4.1-20050723
first failing snapshot is:  gcc-4.1-20050730
