Ahh good example.  I hadn't thought of that particular case.

At first, no (I was using --trace deep), and I occasionally got
assertion failures due to not using .decldebug (i.e. missed final
events), but I got the same result (minus the assertion failures)
afterward.

To check my sanity I downloaded the test suite and ran the decldebug
tests; they all passed.  So there's some odd interaction between my
code and dd; I'll try to track it down and post a bug report (or fix
my code!) later.
