While Go allows interior pointers, I don't think what you say is true. runtime.KeepAlive was added exactly to prevent GC from collecting the struct when only a field pointer is stored. Take a look at this blog post, for example: https://victoriametrics.com/blog/go-runtime-finalizer-keepal...

I don’t believe that’s the case based on the example in the blog post. The fd field in that struct was passed into the later function by value (i.e. as an int, not an *int), so there was no interior pointer in play at all.

You are right; I stand corrected
