match *enum {...} produces C error

[islonely]

Describe the bug

C error produced from trying to dereference enum variable as the V error in #23313 advises.

Reproduction Steps

enum Foo {
    zero
    one
}

fn main() {
    shared foo := Foo.one
    rlock foo {
        match *foo {
            .zero { println ('0000') }
            .one { println('1111') }
        }
    }
}

Expected Behavior

Expected code to compile and print 1111.

Current Behavior

================================================================
(You can pass `-cg`, or `-show-c-output` as well, to print all the C error messages).
builder error: 
==================
C error found. It should never happen, when compiling pure V code.
