[Octave-bug-tracker] [bug #57464] patch plot of quadrilateral ill shaped

[Rik]

Follow-up Comment #7, bug #57464 (project octave):

A quick way to guarantee whether code is reached is to add


assert (0);


before the code in question.  You may need to add


#include <cassert>


as well for access to the library function.

This will immediately abort the program as soon as the assert is reached.  It
is a somewhat clumsy debugging mechanism, but sometimes, particularly if there
are a lot of callbacks, I don't always trust the debugger gdb to guarantee a
stop at a particular point.
