Hello,

I am trying to execute a loopback query in embedded python:

CREATE FUNCTION myfunc() RETURNS TABLE(n STRING) LANGUAGE PYTHON { res = _conn.execute("SELECT max(d) FROM mytable;")

result = dict() result['n'] = str(res) return result };

When accessing the object ‘res’, mserver5 outputs ‘segmentation fault’ and exits. I think that the issue is in using the max() function in the query, if I leave that out everything works fine. The function:

CREATE FUNCTION myfunc() RETURNS TABLE(n STRING) LANGUAGE PYTHON { res = _conn.execute("SELECT d FROM mytable;")

result = dict() result['n'] = str(res) return result };

outputs a correct dictionary.
