Customer Impact
When struct's field is passed by reference, any update made to the
refvariable doesn't change the original value of struct's field. Additionally, if try to retrieve the value of the parameter, it returns wrong result.Testing
The fix contains a test.
Risk
Low, the issue arises in very specific scenario when we decide to promote struct, later undo the promotion and one of the field is used as return result.
