> I think this patch will break the purpose of the test. We should fix the issue instead of hide it from tests.

The test ensures that json calls Py_EnterRecursiveCall() which relies on sys.getrecursionlimit(), see the commit below.

There is no generic fix for C stack overflow. The tes failed on Windows XP which is no more supported, I don't think that it's interesting to spend time on it.
