Assertion failure with @sizeOf() in switch expression

[17dec]

Zig Version

0.11.0-dev.1280+4b3291764

Steps to Reproduce and Observed Behavior

test "switch sizeof" {
    switch (0) {
        @sizeOf(struct {}) => {},
        else => unreachable,
    }
}

Produces the following error:

thread 27953 panic: reached unreachable code
