patch 8.2.4573: a nested function is compiled for debugging without context
Problem: A nested function (closure) is compiled for debugging without
context.
Solution: Check if a nested function is marked for debugging before
compiling it. Give an error when trying to compile a closure
without its context. (closes #9951)
