temporary-iterator

Detects when you're using using functions returning iterators (eg. begin() or end()) on a temporary container.

Example

// temporary list returned by function
QList<type> getList()
{
    QList<type> list;
    ... add some items to list ...
    return list;
}

// Will cause a crash if iterated using:

for (QList<type>::iterator it = getList().begin(); it != getList().end(); ++it)
{
  ...
}

because the end iterator was returned from a different container object than the begin iterator.
