segmentation fault with loopback query

6 Jun 2016

      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.

Stefano
