@Centril Yeah I'm able to reproduce, trying to figure out how to debug wasm currently...

[Mark-Simulacrum]

FWIW I was able to reproduce as well, see some discussion/history on Zulip.

This snippet makes the test run fine on wasm I believe, so we probably just want to ignore the test (it looks like the sizes for wasm are different, probably due to some underlying struct -- here is a diff of -Zprint-type-sizes with i686-unknown-linux-gnu vs wasm32-unknown-unknown: https://gist.github.com/Mark-Simulacrum/cd7d2532c12f38584544e7b0ca07b4b6, but that seems to suggest that the difference is not in an underlying type but rather optimizations or how we do layout of generators...).

    assert_eq!(1028, std::mem::size_of_val(&single()));
    assert_eq!(1028, std::mem::size_of_val(&single_with_noop()));
    assert_eq!(3080, std::mem::size_of_val(&joined()));
    assert_eq!(3080, std::mem::size_of_val(&joined_with_noop()));

[tmandry]

@agnxy The tests should pass with my suggestion applied.

[agnxy]

Thanks a lot @tmandry and @Mark-Simulacrum I'm reading the zulip topic to learn about wasm.
