@danhhz can you help me understand how concerning this assertion failure is?
Looks like the panic is coming out of some code that is only run under debug_assertions. It's one of those "do a thing the tricky, fast way and the obvious, slow way and make sure they give the same answer" sort of things. If they were giving different answers, that would be quite concerning, but it looks like the failure is actually that an assumption of the obvious, slow way is being violated.
Overall, definitely something for us to look into, but doesn't seem especially concerning yet that this would indicate a bug in prod.
What version of Materialize are you using?

What is the issue?
Seen in https://buildkite.com/materialize/tests/builds/74892 with ASan enabled, so different timing (https://github.com/MaterializeInc/materialize/pull/24888):
