That isn't necessary.  It's included indirectly by mysql++.h.

You might as well say 'using namespace mysqlpp' here as well.

Try use() here instead of store(), and put the result in a ResUse object.

You can catch this one by const reference, which is more efficient, and 
may stop the crash.

Clearly a segfault is happening.  It would be nice if trying to dump the 
error didn't cause it, but you ought to check things like passwords, 
table names, etc.  I think you're not connecting to your database 
correctly, or using it correctly.
