Comment:

 I am unable to reproduce this issue using valgrind by adding the following
 test to format_test_wstring.cpp:
 {{{

 +#endif // wformat tests

    return 0;
  }
 }}}

 The method in which memory leak detection was determined is missing from
 the original bug report.After building debug and then running valgrind on
 it, there were no leaks.  As such I am resolving this as "worksforme".
