So in plainer language, there are a few non-mirrored (but possibly 
available as Cygwin Ports) apps that lose the link, so to say, with 
their libs and consequently can't run without stackdumping. I figured 
asmuch, and since I needed Some Kind of Exiv2 working in my Cygwin 
install, I went ahead and built the 0.22 version from a tarball  
downloaded from the author's site. It worked. No more stackdumps.

On this last: since reading somewhere that a lot of mirrors and 
repositories don't keep up with the latest versions of things as Exiv2, 
I've been taking the time to obtain the latest source from the author's 
site. For instance, Ubuntu's repos still had version 0.18 of exiv2 from 
when it was made available o the beginning of 2010; in the same space of 
time Andreas Huggel, the author and chief maintainer, had written two 
newer versions and one or two developer snapshots. This isn't to cast 
aspersions on the folks who decide what gets on mirrors or aptitude 
repositories, but simply to say I've found it much more practical just 
to "go to the site" for the "latest-greatest" on this and quite a few 
other things.
