+Subject: [PATCH] fix stack overflow in HandleNode() (CVE-2017-5950)
+
+simply set a hardcoded recursion limit to 2000 (inspired by Python's)
+to avoid infinitely recursing into arbitrary data structures
+
+assert() the depth. unsure if this is the right approach, but given
+that HandleNode() is "void", I am not sure how else to return an
+error. the problem with this approach of course is that it will still
+crash the caller, unless they have proper exception handling in place.
+
+Closes: #459
