That is not true.  It simply depends on whether they are one program or
not, which is a human-level concept, and not a technical one.  There is
no "magic boundary" at which the GPL would neve cross.

For example, if you were to split GCC into two executables, one which
parsed and generated intermediate code, and another which did
optimization and codegen, the result would still be the one GCC, covered
by the GPL.  And this is true even if you then write your own version of
the first part, implementing your seekrit proprietary language: the GPL
on the back end would require that the *whole program* be distributed
under the GPL, any separation into different executables

There is nothing in the GPL about "running on the same CPU" or
"client/server" exceptions.  If you use GPLd code, then the *whole
program* (whatever that is, it is a human-level concept requiring
understanding and not rote following of rigid rules) must be
distributable under terms no more restrictive than the GPL itself.
