suggestion: I don't know how long this test runs, but we could try to make it
faster by lowering the stack-limit with a flag (if it still reproes then).

It already runs in 0.04s, so I think it's not an issue.

Acknowledged. Agreed. :)

-function f() {
-  super.x();
+// Should not crash in ASAN.
+function shouldThrow() {
+    shouldThrow(JSON.parse('{"0":1}'));
 }
