Stage2: Invalid execution of comptime code

[misanthrop]

Zig Version

0.10.0-dev.3475+b3d463c9e

Steps to Reproduce

Try compiling the following code with zig test -fno-stage1 -fLLVM comptime-bug.zig

const std = @import("std");
const S = struct { x: [4]i8 = std.mem.zeroes([4]i8) };
const M = struct { x: [4]S = std.mem.zeroes([4]S) };

comptime {
    var res = M{};
    @compileLog(res.x);
    for (.{1, 2, 3}) |i| res.x[i].x[i] = i;
    @compileLog(res.x);
}

Expected Behavior

Output should be

comptime-bug.zig:7:5: error: found compile log statement
    @compileLog(res.x);
    ^~~~~~~~~~~~~~~~~~

Compile Log Output:
@as([4]comptime-bug.S, .{ .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 0, 0, 0 }} })
@as([4]comptime-bug.S, .{ .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 1, 0, 0 }}, .{.x = .{ 0, 0, 2, 0 }}, .{.x = .{ 0, 0, 0, 3 }} })

Actual Behavior

Output is

comptime-bug.zig:7:5: error: found compile log statement
    @compileLog(res.x);
    ^~~~~~~~~~~~~~~~~~

Compile Log Output:
@as([4]comptime-bug.S, .{ .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 0, 0, 0 }}, .{.x = .{ 0, 0, 0, 0 }} })
