Follow-up Comment #8, bug #55523 (project octave):
In C++, the initialization value can be the result of a function call or a
global variable. But, of course, global variables have much different
semantics in C++.
https://en.cppreference.com/w/cpp/language/default_arguments:
The names used in the default arguments are looked up, checked for
accessibility, and bound at the point of declaration, but are executed at the
point of the function call...
In any case, I agree that it is probably best to be conservative here and only
accept constants as initialization values.
