Log: Fixed bug #61212 (PDO ODBC Segfaults on SQL_SUCESS_WITH_INFO).

Description:
------------
PDO ODBC segfaults when a column less than 256 bytes are retrieved (has to be SUCCESS_WITH_INFO).
The buffer is allocated with the assumption the retrieved column is greater than 256 bytes. When a
column with say 150 bytes are allocated, the code tries to write 256 bytes to the buffer and results
in a segfault.

The segfaults go away by ensuring the column length is checked before assigning characters to the
buffer.  

Test script:
---------------
<requires a column coming from the db with a character encoding issue and length less than
256>




Expected result:
----------------
Should work regardless of the length of the column data

Actual result:
--------------
Segmentation Fault


------------------------------------------------------------------------
