The following code should generate a compiler error stating how the same discriminant value is assigned multiple times.

enum Foo {
    Bar = 1,
    Qaz = 1,
}

fn main() {}

But it seems to generate no errors on gccrs.

which compiler flags are you using ? I guess -Werror flags would help?
Would love to know a bit more about the issue, regarding the versions and stuff , I guess it has been updated.
