[Bug c++/33361] New: ICE in find_outermost_region_in_block, at tree-cfg.c:4803

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

Hi,

I'm getting an
    internal compiler error: in find_outermost_region_in_block, at 
    tree-cfg.c:4803
in -fopenmp mode with g++ 4.2.[012]. g++ 4.3 produces no error.

Andreas
