    Description

      Moving the cursor on "iterator" will crash qt creator in this code:

      #include <string>
#include <map>
#include <set>

int NIProperties::serialize(NIArchive &archive)
{
    for(std::map<const char*, int, ltstr>::iterator it = _map.begin(); it != _map.end(); it++)
    {
        existingKeys.insert(it->first);
    }
    for(std::map<std::string, NIVariable*>::iterator it = map.begin(); it != map.end(); it++)
    {
        std::pair<std::set<std::string>::iterator,bool> r = _str.insert(key);
    }
    return 0;
}

      Backtrace:

      Program received signal SIGSEGV, Segmentation fault.
