Does it reproduce with nightly?

[llebout]

duplicate? #66868

[llebout]

@Centril Looks like not! That's great.

[Centril]

Cool; closing the issue then. Thanks :)

[llebout]

@Centril Are you going to make a point release?

[Centril]

It's unlikely since it's an ICE in already erroring code (at least from what I can surmise from the backtrace).

[llebout]

@Centril Indeed, and I see. Didnt know about such policy.
