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.
