Update of bug #32682 (project octave):

              Depends on:                         => bugs #32980

Follow-up Comment #4:

The problem appears to lie mostly with the fact that OpenGL and the FLTK
backend use single precision variables for axis positioning.  When these
values overflow the behavior of the plotting functions, such as title, becomes
indeterminate.  See bug #32980.  

It is still true that the interpreter shouldn't segfault and perhaps there
needs to be some Octave code written to identify when high dynamic range plots
are being attempted and stop this behavior.
