[Octave-bug-tracker] [bug #29491] recursive source() causes segfault

[John W. Eaton]

Follow-up Comment #4, bug #29491 (project octave):

Yes, you could just count recursive invocations of the source function
itself.  The reason I proposed the other solution is because it would be more
consistent with what currently happens with script files that are recursive. 
For a script file that calls itself, the recursion limit is
Vmax_recursion_limit.  For a pair of mutually recursive scripts, it is twice
that number.  If you just count calls to source, you will get
Vmax_recursion_limit calls to source itself, which will mean half as many
allowed calls for a pair of mutually recursive scripts that call each other
via source as would happen if they call each other directly using the script
file execution feature of Octave.  I agree that this is not likely to be a
widely used feature, but the solution I'm proposing isn't all that complex, so
why not make the two cases behave the same?
