[2020/07/02 17:58:05.557] Fatal Python error: Aborted

      https://evergreen.mongodb.com/task/mongo_python_driver_tests_python_version_rhel62_without_c_extensions__platform~rhel62_auth_ssl~noauth_nossl_python_version~3.4_c_extensions~without_c_extensions_coverage~coverage_test_4.4_replica_set_a075eb798f97379cec2d7d1cc971a774ccaeb9b7_20_07_02_17_53_08

      This seems to be the same issue described in https://bugs.python.org/issue25222 and PYTHON-996. The new thing here is that the error is now happening on Python 3.4 as well. Given these two quotes on the python bug ticket:

      Well, Python has no perfect protection again stack overflow. It's only best effect.

      and

      The problem only occurs for me when testing with a MongoDB instance running. Running background threads seem to be a key requirement for reproduction. Note also that this problem does not reproduce when using PyMongo's C extensions, only when using the pure python BSON encoder.

      I suspect this cause of this issue may be that the Python interpreter itself uses some stack space when yielding the GIL between threads. So if we get unlucky and the thread running bson.encode() yields the GIL near the stack limit, we'll run into the fatal stack overflow. This issue does not appear when encoded with the C extensions because this C encoding code path will not yield the GIL.
