I think I've pointed out that the *majority* of the bug reports here are
"crappy", right?

I am trying to reorient your (and everyone's) thinking.  You spent a
long time debugging.  That is appreciated.  However, you are a member of
the mailing list called 'cygwin-developers'.  That means that you should
have committed, at some point, to be contributing to cygwin.  I usually
ask people if they have built cygwin when I grant them the awe inspiring
membership in this mailing list.

The answer has to be "yes" in order to gain membership.  Maybe I didn't
ask the question of everyone.  If not, then I guess you're off the hook.
If you did commit to having built cygwin then I think I have a right
to assume that you should be able to generate a debugging version of
cygwin and provide an analysis of any stackdump file.  That shouldn't
be that big a deal.  It takes an extra five minutes to figure out
exactly where the program crashed from the stackdump file.

If you are not set up to do this or don't want to do this then send "it
crashes" bug reports to cygwin AT cygwin DOT com.  I don't want to get into the
habit of bug reports with no analysis here.  That is not the intent of
this mailing list.
