It does not rely on any base address per se. It *does* reply on the base
address being consistent between forked/spawned and exec'd parent and
children. That means that the base address must be one of the following:
a) Whatever is in the .dll, in all cygwin processs (for a given process
hierarchy). (ie it can be different for different invocations of
b) Relocated consistently on the fly in all cygwin processs (for a given
process hierarchy). (ie it can be different for different invocations of

Can you get process explorer to show their address space - get them to
fail, and stop rather than terminating (usually there is a dialog you
could leave open or you can use the CYGWIN debug flags).
