I'll check it out.
On second thought, though:
Unless some of your users have already run into this bug (quite
possible - our Intel 11.1 builds triggered it) you might want to hit
it with your test suite before pushing it out. I've managed to get
one gcc build and one intel build with LIBMESH_DEFINE_HASH_POINTERS so
far, but haven't given it any serious regression testing yet.
