How does -Zunstable-options change behavior of this test?

I assume the thing that causes that test to fail is not -Znunstable-options, but just debug assertions. We don't test those in CI afaict.

It would have caught the original ice which is reason enough to add it imo.

I do run x.py test with debug assertions from time to time.

No, I am asking why you believe -Zunstable-options would have caught the original ICE? -Zunstable-options afaict does nothing on its own -- it's required to pass other unstable flags, but it doesn't do anything behavioral on its own.

I have been reporting several ices where -Zunstable-options was crucial to reproducing the ICE, with no other flags being involved.

As to why that happens, no idea 🤷

Is this necessary?

I like to have some context in the test what the ice looked like

Ah lol.
The original repro needed a tab on a very specific place for some reason 🐙
while reducing the ice would go away if I replaced the tab with a space
