[Bug c/36154] New: internal compiler error: in get_constraint_for_component_ref, at tree-ssa-structalias.c:2727

["patrick at motec dot com dot au" <gcc-bugzilla at gcc dot gnu dot org>]

I'm encountering an internal compiler error with the gcc 4.3.0 release. I don't
think this is a duplicate of any other bugs.

Here is the command and subsequent output:
