I attach a strack trace obtained with the current default "d0f9826f677d+".

I'm reporting a segfault in the same vein than bug #44875 so it might be hard for others to reproduce.

If I run this executable:

I get a segfault each time with 4.2.1:

and a segfault about one in ten times with 4.5+:

The script was initially much longer but I reached the point where it doesn't crash any more if I remove a single line. Not sure each of them is necessary as it might just be a race condition.

I couldn't initially reproduce it from the Octave command line but just noticed I actually can if I paste all of the above followed by delete(F):
