Could it be caused by https://github.com/dotnet/runtime/pull/112206 @tannergooding ?

[tannergooding]

@matouskozak, I wouldn't expect so without it also triggering for Mono on other platforms -or- there being some pre-existing Mono Arm32 bug that the change just happened to expose.

All the PR does is handle the intrinsic and import it directly as the relevant IL opcode, there's not much room for it to have a mistake.
