psqlodbc.dll (version:7.03.02) crash error

Hello,

Now I get the psqlodbc.dll crash error:
"unhandled execution in xxx.exe (PSQLODBC.DLL):
0XC0000005: Access Violation"

I wrote a function in C++ to insert rows including
binary data (bytea data type ) into table.

This error was happened in SQLExecute(hStmt) when the
second time to perform the insert operation, but the
first time is always ok.

Please help me avoid this error.

Thanks,

Vivian
