This turns out to be a tough issue which I have had to hand off to
those with a lot more Tcl/Tk expertise than me (see discussion on the
plplot-devel list).  The upshot is that the
test_wish_standard_examples target (the one that segfaults at the very
end of all the examples in the process of exiting) has been
(temporarily until the segfault is fixed) taken off the list of
targets that are run by the test_interactive target.  I have also
fixed some Tcl-related build-system issues in the installed examples
tree.  The result is now (revision 12710) I can run "make
test_interactive" for either the core build system or the installed
examples build system without encountering any errors, and I hope that
is the case for you as well on your Fedora platform.
