If we aren't going to try to work around the bug, I agree that
removing that example (or replacing it with a less buggy one?)
is a good idea.

I tend to agree with Peter that trying to work around a bug that
isn't ours and that we don't fully understand is not going to
be very productive.  What is the argument, other than observation
of a small number of test cases, that these other subroutines
don't have bugs of their own?
