Some consensus issue occurred after merge this pr in my repo
#23381
but I am not sure it will occur in go-ethereum

It is fixed by this CortexFoundation/CortexTheseus@cb78eb6
I hope it will do some help

The change your proposing actually reverts a fix to a consensus issue. The issue was that returndata was modified during the memory copy, in certain conditions.
See #23518 -- more explanation, the so far DRAFT post-mortem of the incident.
