patch 9.0.1988: Vim9: potential use-after-free for class members
Problem: Vim9: potential use-after-free for class members
Solution: Use the class-related grow array for storing the
member type instead of using a temporary type
list grow array
Use the type list grow array associated with the class than using a
temporary type list grow array to allocate the class member type.
For simple types, a predefined type is used. For complex types, the type
is dynamically allocated from a grow array. For class variables, the
type grow array in the class should be used. So that the lifetime of the
type is same as the lifetime of the class.
