Travis Vitek commented on STDCXX-577:
-------------------------------------
The leaks mentioned by the valgrind report are potential leaks in purify. The
locale that is imbued on std::cout.rdbuf() owns a StockXchange facet that is
allocated on the heap. If/When the locale is destroyed, the facet reference
count would be decremented and the object would be deallocated [if appropriate].
My solution is to restore the streams locale before main returns. This prevents
the facet from being in use at program termination. This fix is included in the
above patch.

> It is pretty obvious from looking at the source that memory is being leaked.
> The destructor for StockXchange doesn't deallocate memory allocated in
> StockXchange::add(), and the sl_pairs allocated in main are never deallocated.
