Fixed bug #69381 out of memory with sage odbc driver

Frederic Marchal · weltling · commit f505d112074d · 2015-04-28T15:08:53.000+02:00
This is just a hotfix as there are still drivers with no full
ODBC 3.x support. This patch origins from bug #68350 which was
solved by the proper 3.0 migration, another driver (Sage)
turned out to have the real issue.
