First thing of course is loading octave-workspace and inspecting the
variables. Among them should be the current value of the counter
variable of your loop. Use this and the other loaded variables to
repeat the commands in the loop for this counter value. This could
trigger the crash if a single command unconditionally causes it.

If not, you can run Octave in a debugger or similar thing and obtain a
backtrace at crash time, which might give a clue to someone.

If the code in the loop is only a few lines long, you could post it
and maybe someone finds that something looks suspicious.
