The 'c_str()' method of the STL 'basic_string' class template
returns a pointer to free memory when called against a
string returned by the 'str()' method of the 'basic_ostringstream'
class template. ISO/IEC 14882 [21.3.6] indicates pointers returned
by 'c_str()' should be good until the next non-const member of the
string object is called.
This behavior is confirmed by both 'purify' and 'mudflap'.
The same test case runs clean with 'purify' on Solaris 8
with the Sun Studio 5.4 compiler.
