I'll adjust the code to simply use in_txn flag for the moment to avoid the
structure change.

Here you are changing a structure which is allocated and initialized in
a driver and then read from the PDO core. PDO core will therefore read
invalid memory when a driver compiled against 5.3.2 is used in 5.3.3
while we usually guarantee binary compatibility in bug fix releases.

This for instance affects distributors or MSFT's sqlsrv driver.
