Looks like this assert appeared before, in #12769, but it's not clear from that issue if it just "went away" or was fixed.

EgorBo · 2023-02-16T19:58:13Z

just a note before I'm blamed again for "Frozen" 🙂 that this assert is a typical sign of a classic gc hole, it's just that on 64bit platform we 99% hit the "padding is not zero" assert instead.

BruceForstall · 2023-02-17T00:24:19Z

This failure is showing up in lots of different platform/architecture/stress combinations in runtime-coreclr libraries-jitstress-random:

BruceForstall · 2023-02-17T03:53:49Z

Looks like all configurations, even non-stress configurations, are failing with this assert in the runtime-coreclr libraries-jitstress pipeline:

This is a new test introduced in #81006 along with extensive other changes.

@steveharter Can you disable this test ASAP (and any other test that might fail in the libraries-jitstress pipeline)?
