@jakobbotsch can you please take a look at the Fuzzlyn-arm64 failure, is it worth investigating?

@jakobbotsch can you please take a look at the Fuzzlyn-arm64 failure, is it worth investigating?

I've seen it a few times, I don't think it's related to this PR. Seems like either Fuzzlyn can generate extremely large structures or something else is wrong. It's probably the former.
