Hello,

There is a bug http://tracker.firebirdsql.org/browse/ODBC-183

Stdout:

*terminate called after throwing an instance of
'IscDbcLibrary::SQLError' what(): std::exception *

I've investigated a problem and I think that in
IscDbcLibrary::IscConnection::getCountInputParamFromProcedure function
exception is thrown and in the process of stack unwinding the second
exception is thrown in destuctor:



*IscResultSet::~IscResultSet() { close(); } *

After this the program is terminated.
Help me, please, I must know if it is our problem or FB ODBC Driver problem.
