FWIW, my problem is a combination of a problem with our container based
linkage of statements and our nested control structures.    We've got
a container in the IL which has a dangling pointer to a de-linked basic

As it turns out that mostly mucks up tree dumping and not real code, but
it's still extremely annoying.  I thought I had it fixed, but the changes
caused problems elsewhere.
