new knownEmptyContainer FPs

[Martin]

Hi,

several new FPs of the following kind appeared in our code due to the most recent commits:

void foo()
{
   std::vector< ptr1 > const potentialRoutes = m_RouteData.getPotentialRoutes( id );
   for ( ptr1 const & potentialRoute : potentialRoutes ) {}
}

-->

style: Iterating over container 'potentialRoutes' that is always empty. [knownEmptyContainer]
   for ( ptr1 const & potentialRoute : potentialRoutes ) {}
                                       ^

cppcheck can't assume at this point that the container will be empty.

worked with: 3ba69145635a4ff01d4cec65a0293f5b8ccd13b0
occured with: 64a7ba3c4c01cf912dfe8617a94cbe6d00667523

Could you please check?

Thanks,
Martin

Thanks for reporting, ticket is here: https://trac.cppcheck.net/ticket/10951

Since you report quite often, maybe @danmar could set you up with a trac account?

I'd use it if I had one, but last time I tried to get one ... mh I don't remember, was some years ago .
