Problem in Re-using the prepared statement

Desc: i have a problem executing the prepared statement more than once. 1st
time it executing correct and when i try to execute same prepared statement
next time it is failed giving the error like this.

*details:* i am executing a prepared statement with binding some parameters
,after executing i am resting the prepared statement and unbinding the
parameters. when try to execute the same prepared statement it is giving
the error :"27:Error fetching numeric attribute: ColAttribute for this type
not implemented yet". i am using libodbc++ library. when i debug it is
going wrong at

*Line* :ResultSet* rs=ODBCXX_OPERATOR_NEW_DEBUG(__FILE__, __LINE__)
ResultSet(this,hstmt_,hideMe);

Error: "27:Error fetching numeric attribute: ColAttribute for this type not
implemented yet"

PostgreSQL version number you are running:

How you installed PostgreSQL:PostgreSQL 9.3.5, compiled by Visual C++ build
1600, 64-bit

Changes made to the settings in the postgresql.conf file: No

Operating system and version:windows 8.1 (64-bit)

What program you're using to connect to PostgreSQL:ODBC 3.5 (libodbc++)
library

Is there anything relevant or unusual in the PostgreSQL server logs?:No

For questions about any kind of error:

What you were doing when the error happened / how to cause the
error:"27:Error fetching numeric attribute: ColAttribute for this type not
implemented yet"
