;; Test case for correctness of reading state with the presence of parameters passed on (machine) stack.
;; Usage: Run with a backend with support for OSR. Interrupt execution randomly.
;; Should see the stack frame for `$foo` to have locals `[0] = 1, [1] = 2, [2] = 3, [3] = 4, [4] = 5, [5] = 6, [6] = 7, [7] = 8` with high probability.
;; If the logic for reading stack parameters is broken, it's likely to see `[0] = 1, [1] = 2, [2] = 3, [3] = 4, [4] = 5, [5] = ?, [6] = ?, [7] = ?`.
