  • SR-11692 Compiler crash in property wrappers

Issue Description:

I’ve been devising a @propertyWrapper that has an argument that can be omitted and accepts the default value inline.

The wrapper crashes compiler when the variable is declared in a class and the argument is omitted. Does not happen when used as a static variable in enum or when providing the optional argument.

See attached code and crash report.
