Please read and follow the Cygwin problem reporting guidelines at
<http://cygwin.com/problems.html>, especially the part that asks you to
attach (as an uncompressed text attachment) the output of "cygcheck -svr"
on your system.
In the absense of that output, a WAG would be that you've encountered a
particularly devious what we dub <http://cygwin.com/acronyms/#3PP> -- a
set of tools that bundles parts of Cygwin. The deviousness manifests in
that their cygwin1.dll is apparently renamed to something else. However,
that still doesn't avoid the shared memory region conflicts, since the
shared region id is Windows-global.
Looking at the output of "cygcheck -svr" requested above should confirm or
deny this guess. At that point we can work on further steps in isolating
