@MichalStrehovsky Have you seen this before?

[MichalStrehovsky]

@MichalStrehovsky Have you seen this before?

We have #72645 for Linux Arm64. That one is for NativeAOT-compiled crossgen2 though.

We don't AOT compile crossgen2 used in testing, so this sounds like a possible CoreCLR bug.

Hard to say if they're related. Could be.

[AntonLapounov]

We need to collect crash dumps.

[MichalStrehovsky]

We haven't seen it on Mac arm64? NativeAOT doesn't support that and we ship crossgen2 on top of CoreCLR there

[AntonLapounov]

This might be a dup of #75041. Closing as non-actionable.
