Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Destroying Query object causes unhandled exception: msg#00027

db.mysql.c++

Subject: Destroying Query object causes unhandled exception

Hello all,

right to the point. I have the following code in my application:

try
{
mysqlpp::Connection sqlCon( db, host, user, passwd );

mysqlpp::Query query = sqlCon.query( );
}
catch ( const mysqlpp::BadQuery &e )
{
cerr << e.what( ) << endl;
return;
}
catch ( const mysqlpp::Exception &e )
{
cerr << e.what( ) << endl;
return;
}

With this code it is possible to use the connection and the query object to
manipulate database.
But when the application is going out of the try block and tries to destroy
Query
object it stops in "dbgheap.c" with unhandled exception or assert says:

Expression: _BLOCK_TYPE_IS_VALIDE(pHead->nBlockUse)

I have found this type of error on google but without any replyes. I've
been playing more with this code and tried to set up new project. In new
project it is without error.

Therefore I thought, I have problem with memory leaks. But it was
strange because the application runs without any error. So I've commented
everything before that try block but it haven't helped.

Does anybody have any idea what might be the problem? Thanks in advance!
