addresses for expression values are not that useful, the value of
what they point to is what i would look for if i saw a troublesome
address. I haven't looked at the brelease function signature, but if
you know it, that would be useful when looking at the expressions.
in fact i'm not sure what the expressions are. and what the meaning
of an empty one is. they look like vars in scope. can you include
registers? those help too sometimes. would a different format help?
something less verbose and parsable like (fear i say) JSON. i get you
intend to parse this somehow. but JSON is a little better than XML
and less cluttered.

where is this tool you're working on? can i looksee?
