This is about SEH __try/__except/__finally really, isn't it? ;-)

You'll need to have an abnormal/EH edge coming into it, if I understand
things correctly, for dataflow to realise it can be invoked by some
non-standard path. Take a look in tree-eh.c; seems what you're doing is
pretty similar to how C++ try/except is implemented.
