# Haven't tried this yet.
#    -enable-checker alpha.unix.PthreadLock

# This one gives a false positive on every strcmp.
#    -enable-checker alpha.core.PointerSub

# This one hates it when we stick a nonzero const in a pointer.
#    -enable-checker alpha.core.FixedAddr

# This one crashes sometimes for me.
