Zig Version

0.15.1

Steps to Reproduce and Observed Behavior

test {
    const gpa = testing.allocator;

    var list: std.MultiArrayList(struct { void }) = .empty;
    defer list.deinit(gpa);

    list.append(gpa, .{{}}) catch unreachable;
}

const std = @import("std");
const testing = std.testing;

Testing this code causes the build error:

*\zig\x86_64-windows-0.15.1\lib\std\multi_array_list.zig:625:26: error: extern struct fields cannot be marked comptime
            break :entry @Type(.{ .@"struct" = .{

Expected Behavior

MultiArrayList must works with a tuple that containing void.
