There's some chance that this is a Cygwin bug. If you can narrow down the problem to a specific code snippet in octave, you may be able to extract a very simple testcase in plain C which allows to reproduce the problem without the zillions of octave/fltk code lines. That would be most helpful in case it is a Cygwin problem.
