It is taken from the heap (by chunks) on some (most?) platforms.
On others, it is allocated on the primary stack.
See package System.Parameters.

As far as I know, the only things allocated on the seconary stack are
function results of caller-unknown size (as in function(...) return
String), and some controlled/finalization-related things.
