assert: RangeError: Maximum call stack size exceeded is still present

Version: tested on v6.9.1 and v8.0.0-pre, but it seems like all versions are affected.
Platform: Linux 3.16.0-4-amd64 SMP Debian 3.16.39-1 (2016-12-30) x86_64 GNU/Linux
Subsystem: assert

The following code

const a = {}
a.ref = a

const b = {}
b.ref = b

const c = { ref: b }

assert.deepEqual(a, c)

ends up with RangeError: Maximum call stack size exceeded and it seems like changes for #6416 didn't fixed that error entirely.

I'm going to provide the fix in a PR soon.

assert: fix deepEqual RangeError: Maximum call stack size exceeded

var a = [];
a[0] = a;
JSON.stringify(a);
// Uncaught TypeError: Converting circular structure to JSON

@wuliupo

@wuliupo you can't stringify a circular structure. That's by spec and it is completely independent from the issue about the range error.
