[php-maint] Failed to upgrade from deb7u2 to deb7u3

[Clement Wong]

Hi guys,

After I upgraded from deb7u2 to deb7u3, our web servers went down for 
almost a day, the problem seem to come from PDO or php5-sybase, we are 
using PDO to connect to MSSQL server, and any query will try to allocate 
crazy amount of memory even if it is a tiny query.
I have pages of these log, and I've replaced our domain to test. :)
