--- Comment #11 from sandra at gcc dot gnu.org ---
OK, I've been digging around in the code.  do_poplevel() only fills in
BIND_EXPR_BLOCK if stmts_are_full_exprs_p() is true.  I haven't figured out the
control flow that affects the latter predicate or how the vars in a BIND_EXPR
end up associated with some other block, but I understand what a
full-expression is in C++, so I think I can go off and come up with some test
cases to exercise that and figure out what the right thing to do with the tree
coming in to this restructuring is.
