exception in shared libraries

[big4mil]

Hi all,

does somebody has experience handling exceptions within shared libraries on linux?

I can dynamically load my shared library, but if I call a member function in my library which throws exceptions and try to catch it in my main program, I'll get following error:
Program received signal SIGABRT, Aborted.
Terminate called after throwing a instance of 'DBException'.
(In debug mode).

Loading the library in my main app:

typedef DBFactory *create_t();
create_t *create_object = (create_t*)QLibrary::resolve( "./libmylib.so", "create" );
 
	if( create_object )
	{
		qDebug() << "Library loaded!!!" << '\n';
		dbFac = create_object();
        try
        {
            dbFac->checkConnection();  // in this function the exception will be thrown
                                                // but unfortunately the program crashs
        }
        catch( DBException &dbEx)
        {
           ...
        }
	}

typedef DBFactory *create_t();
create_t *create_object = (create_t*)QLibrary::resolve( "./libmylib.so", "create" );
           	
	if( create_object )
	{
		qDebug() << "Library loaded!!!" << '\n';
		dbFac = create_object();
        try
        {
            dbFac->checkConnection();  // in this function the exception will be thrown
                                                // but unfortunately the program crashs
        }
        catch( DBException &dbEx)
        {
           ...
        }
	}
