Fltk is not working on cygwin, so I am skipping it.
Before the automake change there was a switch to disable it
and today is not available , if I am not wrong.
I don't know if fltk is involved at all, but there was a
similar fault reported and corrected about it
https://www-old.cae.wisc.edu/pipermail/octave-maintainers/2009-December/014256.html
Eventually there is a similar problem with another module,
but which one ?

I already identified the changeset, it starts to SIGSEV from
changeset 9981 692ab4eaf965
"clean up top-level variables when exiting Octave"
before that I have no SIGSEV.

Any idea how to further investigate ?
