erroneous behavior with #[cfg]

[joshlf]

The following code results in a parsing error where the 0 character is unexpected.

fn get_usize() -> usize {
        #[cfg(not(debug_assertions))]
        0
        
        #[cfg(debug_assertions)]
        1
}

However, the following code works fine:

fn get_usize_return() -> usize {
        #[cfg(not(debug_assertions))]
        return 0;
        
        #[cfg(debug_assertions)]
        1
}

I think this is a bug in the parser?

Duplication of #38337.
