`@addWithOverflow` with vectors doesn't work when they are from functions arguments

Zig Version

0.10.0-dev.4418+99c3578f6

Steps to Reproduce

To illustrate something like this:

const V = @Vector(2, u8);
fn addVec(_: V, _: V) @Vector(2, bool) {
    var result: V = undefined;
    return @addWithOverflow(V, V{ 2, 4 }, V { 6, 7 }, &result);
}

works fine, while the following:

const V = @Vector(2, u8);
fn addVec2(x: V, y: V) @Vector(2, bool) {
    var result: V = undefined;
    return @addWithOverflow(V, x, y, &result);
}

behaves very oddly

Expected Behavior

For it to compile normally

Actual Behavior

There is this following message: error: expected type 'bool', found 'u1'

    return @addWithOverflow(V, x, y, &result);
           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The following code (the equality test specifically):

fn addVec3(x: V, y: V) bool {
    var result: V = undefined;
    return @reduce(.Or, @addWithOverflow(V, x, y, &result)) == 1;
}

crashes the compiler with illegal hardware instruction.
