Re: psqlodbc crashes while collecting diagnostic records with SQLGetDiagRecW

Dear pgsql-odbc developers,

Windows 10,  psqlodbc 16 (psqlodbc35w.dll), postgresql 11.
Getting certain amount of diagnostic records with SQLGetDiagRecW crashes
the application with memory access violation.

Steps to reproduce:
1. Create procedure:
CREATE OR REPLACE PROCEDURE crashme()
LANGUAGE plpgsql
AS $$
BEGIN
FOR i IN 1..841 LOOP
         RAISE NOTICE 'msgmsgmsgmsg (%)', i;
END LOOP;
END; $$;

2. Use example code in attachments.
3. Application crashes with memory access violation after calling
SQLGetDiagRecW function, with iRecord = 332.
Application doesn't crash if number of iterations in  procedure's for
loop is changed.
Expected outcome: SQLGetDiagRecW would return SQL_NO_DATA when there's
no more diagnostic records.

Regards,
Andrey
