[Octave-bug-tracker] [bug #62017] 5 warnings on unused variables detected by clang 13

[Rik]

Follow-up Comment #1, bug #62017 (project octave):

Are you sure clang is correct about these instances?

I took one example, m_debug_frame, and using grep it is certainly used in
several locations in the code.  On the other hand, the same variable name
"m_debug_frame" seems to be a private member variable of both the
tree_evaluator class and the debugger class.  That's pretty confusing.  Maybe
clang has it right and that m_debug_frame should be deleted from the debugger
class.  Or maybe this has uncovered a larger error and m_debug_frame should be
removed from the tree_evaluator class instead.  Add jwe to the CC list for
this question.

I haven't looked at any of the others.
