There was some recent work done on bug #50025, and the cross-thread error handling was also recently revamped.  It would be worth re-testing to see if this is still an issue.

It is a known issue that FLTK, which runs in the same thread as the interpreter, causes problems when Octave's interpreter is not ran from the main thread.

But from your options I guess you are running pure cli Octave. It would help to determined when this stopped working.

Maybe bug #50025?

I am building on macos 10.14.6 (mojave) with,
among others, the following otions :

 --without-x --with-framework-opengl --with-fltk --without-qt

whenever I try to close a plot I get a segmentation fault :


>> version
ans = 6.0.0
>> graphics_toolkit fltk
>> plot (randn (5))
>> close
fatal: caught signal Segmentation fault: 11 -- stopping myself...
Segmentation fault: 11

I think I had seen the same behavior before, but I thought it had been fixed?
