New issue 2200: RuntimeError: maximum recursion depth exceeded on 4.0.1

Konstantin Lopuhin:

Note that this is not complete yet, but still:
While running our internal app PyPy 4.0.0 was consistently failing with an exception "RuntimeError: maximum recursion depth exceeded" after running for a while, and there was clearly no recursion taking place, and the traceback was fairly short. After updating to 4.0.1 the error seemed to disappear, but now 4.0.1 (on another app) also failed with the same error, but this time it seems very rare. Is there anything I can do to gather more data when I get the crash again? This is not production, so I can add more logging or other things (but it will be hard to check with --jit=off as it seems quite rare).
