Jeff ... thanks for the suggestion. The workaround seems to work just
fine, so I am "un-stuck" again.
Hal ... thanks for looking into this bug. I don't have any urgent need for
the fix though, so whenever it happens is just fine with me. :)
Thanks again!

Interesting, thanks! I'll get this fixed. I don't have a better workaround
than what Jeff suggested (compile this file with gcc).
