I'm now regression testing what I think is a fix, but it would be very
helpful if you could come up with a testcase that I could check in to
CVS (or even just one that I could run). Otherwise I have no way to
know if I've fixed the problem you saw.
The original report provides GDB output, but no source files or
command lines that I could use to reproduce that output.
