Reading or writing a VAR_IN_OUT member of a function block or program instance (e.g. `fbInstance.inOut := 1;`) passed validation and dereferenced an unbound pointer at runtime. Such accesses are now reported as E037, mirroring the existing VAR_OUTPUT scope rule. Binding the variable in a call (`fbInstance(inOut := x)`) remains valid.
