test: use JSON.stringify to trigger stack overflow
Browse files Browse the repository at this point in the history
V8's interpreter performs stack checks both at the call site and at the
function entry. A recursive function could therefore trigger stack
overflow at two different source locations. Instead of recursion, call
JSON.stringify on a deeply nested array.
