No, I think most real programs using MySQL++ do it that way. It's on
the stack in the examples just to keep them simple.

Actually, the cpool example keeps its Connection objects on the heap,
too. It's not obvious because we use the default creation mechanism
in ConnectionPool::create(), rather than provide our own.

There's your bug. MySQL++ owns the option objects after you pass them
to Connection::set_option(). If you delete them yourself, you get a
double-delete, which is what's crashing your program.
