// Don't report the over-recursion error because if we are blowing the stack
// here, we already blew the stack in JS, reported it, and we are creating
// the saved stack for the over-recursion error object. We do this check
// here, rather than inside saveCurrentStack, because in some cases we will
// pass the check there, despite later failing the check here (for example,
// in js/src/jit-test/tests/saved-stacks/bug-1006876-too-much-recursion.js).
