      Currently test runs are failing with Python 3.4 and coverage. The error message is at first nonsensical:

      ...
[2021/06/26 01:01:09.453] gcc -pthread -shared -Wl,--enable-new-dtags,-rpath,/opt/python/3.4/lib build/temp.linux-x86_64-3.4/pymongo/_cmessagemodule.o build/temp.linux-x86_64-3.4/bson/buffer.o -L/opt/python/3.4/lib -lpython3.4m -o /data/mci/8522dad9ba0485694eebaebcf0b37dc5/src/pymongo/_cmessage.cpython-34m.so
 [2021/06/26 01:01:10.039] /opt/python/3.4/bin/python3: can't open file 'run': [Errno 2] No such file or directory

      The problem is we're passing coverage arguments ("run --branch") straight to the python interpreter, rather than to the coverage binary. That happened in the following commit, which coincides with the beginning of the CI test failures:

      https://github.com/mongodb/mongo-python-driver/commit/cee37a82e0c230494adbdb3242ae648fe4ce3ef2#diff-3954529b61794d5a9a1f941f18a65a3233f21167980e973154ba1aa8324901a5

      I have no idea why this only breaks Python 3.4. All other versions run as expected.
