There are copies of setup with debug info included at the snapshots
site: <http://cygwin.com/setup/snapshots/>.  It would help greatly if
you could run one of them (ideally the latest) in gdb and get a
backtrace at the faulting location.  You could also attach gdb after the
fault has happened while the error dialog is on the screen.

I tried running addr2line on the above but it seems to return nonsense,
so I think we'd need more context of the call stack.
