Yes, I did warn you about exactly that scenario. Especially dangerous for
32-bit Cygwin you are using, which has scarce address space to rebase DLL's to.
It may work for cloned systems with stable set of applications installed, but
once you encounter a system with somewhat different address space layout, the
things will start to fall apart.

Yes, I've seen it.
