Never mind. I spoke too soon, and my "current CVS" turned out to be not
all that current. The message above comes from pinfo.cc, line 197.
<CYGWIN-TECHNICAL-STUFF>
Would it work if I built my own DLL, with debugging, and inserted a
"try_to_debug()" call before the api_fatal()? Frankly, I've never had
much luck getting gdb to start from the "error_start" setting in
$CYGWIN, but I'll see if I can get this to work unless the above info
helps someone track this down sooner.
