Zig Version

0.9.1

Steps to Reproduce

pub fn main() !void {
    var a: ?i32 = null;
    var b: ?i32 = 1;

    const s = .{a orelse b};
    _ = s;
}

Expected Behavior

A successful build

Actual Behavior

broken LLVM module found: Instruction does not dominate all uses!
  %6 = getelementptr inbounds %"struct:5:16", %"struct:5:16"* %s, i32 0, i32 0, !dbg !17154
  %11 = getelementptr inbounds %"?i32", %"?i32"* %6, i32 0, i32 1, !dbg !17153
