Hi Daniel,

I could not reproduce any of the test failures, neither on x86_64 nor on aarch64. I have blindly fixed the code stub size issue, it seems rather trivial. Would it be possible to open/send me the failing test that triggers vframeArray assert or extract a reproducer that you could publish? I looked at it but could not figure out what could be going on there.

Thanks,
Roman
