This is indeed a bug with debugging and closures; in fact, it was
independently filed a few days ago
(https://github.com/mozilla/rust/issues/8513); it looks like it'll be
fixed very soon.

Yes, this is the same bug and will be fixed with the PR I plan to do
later today. I added your case to the test-suite to make sure that it
indeed doesn't crash anymore.
Compiling with -Zdebug-info should still be considered experimental at
the moment. That being said, we are always glad about getting reports
like this!
