Are you sure there's nothing but an extra \r\n?  It definitely passes
for others, so I'd like to know where that came from.

The extra address means we didn't put the breakpoint at the beginning

the-world-hates-us bug, or we could decide it wasn't a bug.  The
testsuite seems to contain examples of all of the above.
