Working on a nested optimization problem, I noticed that a lot of time was being spent in gradient calls, and a little digging found that doing out-of-place gradients was introducing a type-instability. I followed the advice here , but it does not appear to have helped…see MWE below: using ForwardD…

No, unfortunately I tried that already and it doesn’t change anything…
