This is the sort of narrowing down that helps.

That Win32 error looks more like it is to do with Windows than Cygwin
per se. So what is "Win32 error 6" (apart from a very unintuitive
error message? Google points me at various things, including this:
http://www.freeerrorscan.net/landing/error/error-6.php?t202kw=error%206&m=p&c=3&lpip=538&gclid=CKrViK32uZMCFQ88QwodgQR3DA
which says there are problems with your registry if you get this.
I'm not in a position to give advice on how to fix this. I don't
really know what the best cleanup programs are or how to test their
trustworthiness. But I'd like to know. Also, I don't know whether
to trust that source as being accurate.

this would seem to fit with the hypothesis that this is something amiss
which is not directly related to Cygwin or your program, because the script
does its job. But I wouldn't say it counts as proof.
