"expected optional type" error points at wrong part

[wooster0]

Zig Version

0.10.0-dev.4247+3234e8de3

Steps to Reproduce

pub fn main() void {
    if (1) |x| _ = x;
}

Expected Behavior

$ zig run x.zig
x.zig:2:18: error: expected optional type, found 'comptime_int'
    if (1) |x| _ = x;
        ^

Actual Behavior

$ zig run x.zig
x.zig:2:18: error: expected optional type, found 'comptime_int'
    if (1) |x| _ = x;
               ~~^~~

stage1 gets it right:

$ zig run x.zig -fstage1
./x.zig:2:9: error: expected optional type, found 'comptime_int'
    if (1) |x| _ = x;
        ^
