    Description

      Use of strtok and wcstok are discouraged, I quote from the man page for strtok:

      BUGS
      Never use these functions. If you do, note that:

      These functions modify their first argument.

      These functions cannot be used on constant strings.

      The identity of the delimiting character is lost.

      The strtok() function uses a static buffer while
      parsing, so it's not thread safe. Use strtok_r() if
      this matters to you.

      I discovered this after getting a report from valgrind that StringTokenizer used a delete where it should have used a delete [], however there is no reason just to fix that one problem.

      It should be trivial to rewrite using std::basic_string methods.
