---------------------------------
Resolution: Fixed
> std::stringbuf(const string&) inefficient
> -----------------------------------------
>
> Key: STDCXX-146
> URL: http://issues.apache.org/jira/browse/STDCXX-146
> Project: C++ Standard Library
> Type: Sub-task
> Components: 27. Input/Output
> Versions: 4.1.2, 4.1.3
> Environment: all
> Reporter: Martin Sebor
> Assignee: Martin Sebor
> Fix For: 4.1.4
>
> The basic_stringbuf(const basic_string&) ctor is an inefficient interface
> when constructing a stringbuf object from a character array (as opposed to an
> already existing string object). Each invocation of the ctor causes a
> temporary string object to be allocated for the formal function argument only
> to have it deallocated as soon as the stringbuf ctor returns.
> A basic_stringbuf(const char_type*) ctor overload would be a much more
> efficient interface.
> The same goes for the str(const basic_string&) member function of
> basic_stringbuf as well as for all the stringstream class templates.
