I don't believe it crashes, but the amount of time we're spending in
the aliasing code is, err, on the order of 50% of compilation time
last I checked. Fixing it effectively involves rewriting
tree-ssa-alias.c, which I am doing. However, it'll probably be
several weeks before I have anything ready for serious examination
due to personal commitments, vacation, etc.
