First, kindly <http://cygwin.com/acronyms/#PPIOSPE> keep this on the mailing
list and out of private email.  Thanks.

I've done similar in the past, and it seems to work OK as long as you stop *all*
Cygwin processes before switching directories like that.  Can't have a
background sshd running, for instance.

The first thing that jumps out is SizeOfUninitializedData is 949MB in the good
image but 3227MB (!) in the bad image.  Even on Windows 7 that you're running I
wonder if there's an OS or linker issue building an image with over 3GB of
uninitialized data.

The flip side of that is, why is that different in the two images if you're
using the same commands to build them?  I haven't yet diff'd the two cygchecks
you sent but maybe that'll lead somewhere.
