Fix bug: under specific conditions the closure analyzer could attempt
to "undrift" a block to be a descendant of another block that was
already its ancestor.  This resulted in a SIGSEGV.  The bug is fixed,
and an error check inserted that will provide a more reasonable error
message should something similar happen.
