Your implementation did not compile with my version....
(something lik eimpossible to acces protected typedef in
class FieldContainerFactory..., whatever)
So here's the version without iterators, should be equivalent...
osgExit();
const std::vector<FieldContainerPtr> &fcs =
*FieldContainerFactory::the()->getFieldContainerStore();
int notNull = 0;
for(int i=fcStoreSize;i<fcs.size();++i)
{
FieldContainerPtr fc = fcs[i];
if(fc != NullFC)
{
notNull++;
printf( "Detected living FC!\n");
}
}
printf( "%d out of %d FC's are not destroyed\n", notNull,
fcs.size()-fcStoreSize );
I get 169 out of 180 FC's still living. That's quite a leak.... Will
check. Thank you for the hint!
