This started being hit with db90a849 (build). The last passing build was 7957edc2 (build).

The diff should be within 7957edc...db90a84 .

I'd presume that it's https://github.com/dotnet/runtime/tree/d3be0ecf5a384189acd82f6c5b2631c1db423873

But that's just fixing a minor issue from #94555 (7e51126) and isn't doing anything really unique here, it's just taking an already generic method and dispatching to one of two concrete implementations based on the type of T

[vargaz]

This is probably an OOM. It started with 7e51126, which seems to have a caused the aot compiler to generate way more generic instances. Will investigate.

[tannergooding]

Possibly the same issue as #96630 then. I had initially thought the OOM might be due to the new static virtuals + generics methods, but hitting that even after breaking it apart to 8 concrete APIs.

[vargaz]

It looks like the failure is actually caused by the generic classes added to the test suite i.e. TensorPrimitives.Generic.cs.
