Why is this different from what we, recently, updated on main which is
return []byte(fmt.Sprintf("%s/fwd/%#016p", module, cap))There was a problem hiding this comment.
This one is not breaking for common architectures, by using the same length as before, but for mac m1, it truncate the high byte, to avoid hash mismatch.

But these keys are not in merkle state, so no change would be breaking AFAIK. As long as gas consumption is the same.

exactly, the gas would be different if the encoded pointer has different length, the issue is here: #11726, it seems you have participated in it too.

ethermint feemarket will save the block gas used to merkle state ;D

it works, but it's a breaking one, so can't backport to old versions directly.

Its breaking because it charges a different gas compared to what it was before?

This seems ok given the circumstances, but it'd be nice to indicate in the code this is a temporary patch and should not be replicated. Also, I think the tests should use the two pointer values in the referenced issue
Nice work and thanks for opening up a non-breaking fix

added comments and backward compatibility test.

this is related to #11726 correct? |
yes, a non-breaking backport to make mac m1 able to sync legacy chains. |

This will be included in the next 0.45 point release :) cc @marbar3778 |
