It seems that fuzzing is in fashion. I have received several bug reports
recently that resulted from fuzzers, which are clearly good at inventing
weird patterns that stress the code better than human-invented tests.

I will look at this soon and report back. (But a holiday weekend is
about to happen; I might get to it this week, but it may be next week.)
