SQL 2008 SQLBindCol SQL_C_DOUBLE bug

There seems to be a bug in the new SQL2008 ODBC driver where if you call
SQLBindCol on a numeric column binding as SQL_C_DOUBLE the fetch call fails
with an error: "[Microsoft][SQL Server Native Client 10.0]Numeric value out
of range"

If the BufferLength parameter is 0 the fetch fails.
When BufferLength is set to 8 (size of a double) the fetch succeeds.

According to the MS documentation BufferLength should be ignored for fixed
length data. From the MS ODBC documentation:

"When the driver returns fixed-length data, such as an integer or a date
structure, the driver ignores BufferLength and assumes the buffer is large
enough to hold the data. It is therefore important for the application to
allocate a large enough buffer for fixed-length data or the driver will write
past the end of the buffer. "
