HELP Plz:Memory Leak in std::string

[risa]

hi,
whenever std::string is assigned to another std::string its giving me a memory leak,why is it so....generally std::string's destructor takes care of freeing it.......can anybody help me wht to do to avoid this type of memory leak...???

It might prove helpful if you post the code showing how you actually are using strings ...

Supposing that ProductType is a global scope variable, that might be a bogus memory leak report.
