Re: [go-nuts] Comparison of pointers to distinct zero-sized variables

from a pointer to a zero-sized variable. I don’t want to be stubborn. What would be the issue with at least adding a FAQ entry? I could open a PR suggesting something, although I’m not a native speaker and might not exactly hit the tone of the document. > Am 20.06.2024 um 12:37 schrieb Jan M

Re: [go-nuts] Comparison of pointers to distinct zero-sized variables

Let me start with this: I’m fine with the behavior, it is exotic enough that even the optimizer should be allowed to assume something that doesn’t hold during runtime, since it simplifies things. What I think is at least surprising and at worst lacking is the documentation. It mentions “pointer

[go-nuts] Comparison of pointers to distinct zero-sized variables

I'm observing some strange behavior and could use some help understanding it. The specification says: *“Pointers to distinct zero-size variables may or may not be equal.”* With the following program (Go Playground
