Is it possible that some of your methods have a value-receiver? In that case, they wouldn't be able to mutate any state; *in* the method they'd have different addresses (as the methods act on a copy), but the variables that you call the method on would have the same address.
It is hard to answer these questions, however, without any actual code showing the actual behavior that confuses you; we have to guess both about the behavior and the implementation, which is hard :) On Sat, Dec 9, 2017 at 9:23 AM, <viktor.oge...@gmail.com> wrote: > Hi, > > > I have a problem that I have tried to reduce to a minimal re-producible > example, I have not fully managed but it does show some to me strange > behavior: > > > https://play.golang.org/p/ZCyumUPBos > > > I have a similar set up in a much larger set-up where I seem to see (no > errors reported by race-detector) that sometimes inside a "actionWithState" > the state is not remembered correctly/shared with other instances of > "actionState"s.
