it's not an oom, and it's not an infinite loop, it's just adding n constants is accidentally quadratic, [issue link](https://github.com/nim-lang/Nim/issues/16790)
do you need p to be `const`?
import sequtils
const n = 2000000
const list = toSeq(0..n)
func f(): int =
var i = 0
list[i]
Run
works for me
