Details:

Find two pieces of test code attached:

1) tst_recur.m 

Sets up figures and adds listeners to graphic properties which invoke graphics
callback updater.m

2) updater.m

Graphics callback.


In Octave-5.1 calling tst_recur prints "updating" four times and then returns
to the prompt.  In the development version of Octave "updating" is printed
continuously.

If I uncomment the keyboard statement in updater.m I can see that the stack
depth just keeps increasing on the development branch.
