Okay, thanks. From bug trackers though, it seems it only became 'a problem' once the necessary tests were added to the wasm spec test-suite. And I'd just like re-iterate that...

I don't have an answer of how else to get around it... Maybe the penalty of explicit checks is worth the absolute determinism? Having to exclude an underlying hardware implementation...

Thank you! I feared blockchain maybe the answer :) So, sorry to get a little side-tracked, but I think I'm getting lost among the jargon... I see you are/were affiliated...
