None.  In theory, you should be able to run alias anywhere.  However,
IIRC PTA cannot be applied once we are in SSA form.  That's why you see
it sequenced before pass_build_ssa (Dan, has that changed?).

You seem to have run into a bug in pass_may_alias.  It almost looks like
we are not marking some variable for renaming.  Could you file a PR with
your patch and test case and assign it to me?  I'm currently busy with
something else and I don't want to forget about this one.


Thanks.  Diego.
