Is the backing array used in calls to `unsafe.Slice()` always ignored by the GC?

[winged spoke]

GC in Golang use mark - clean process, if you convert an array from C pointer, GC will not mark it because the memory is not alloced by Golang runtime, thus the array will not be freed by the GC

GC does not care about type, type system only exists in your code or things works with interface, GC only care about the addresses

yes you are right

Go runtime knows which address did it alloced, if it detected any address not under its control, it will just ignore them

if you problem is solved, please type /solved in chat, thanks!

@drowsy plume I have to clearify with this, GC will care about types, when checking pointers from array/slice, but just remind the GC will not check the Go pointers you saved in C array
