segmentation fault with compile_if and an inline function let argument

[undisbeliever]

wiz crashes with a segmentation fault if I use a compile_if attribute that references an inline func's let argument.

(6502 platform)

bank code     @ 0x8000  : [constdata; 0x8000];

in code {

inline func f(let v : u8) {
    #[compile_if(v != 0)] {
        a += v;
    }
}

func test() {
    f(12);
}

}

wiz output:
