.NET JIT potential error?
... +1, definitely a bug - I might have identified the conditions for the error (not saying that nobugz found it because of me, though!), but this (and yours, Nick, so +1 for you too) shows that the JIT is the culprit. interesting that the optimisation is either removed or different when IntVec is...
