-
-What was happening is that the TextStream object is reused for multiple
-different files. Therefore, when one calls setStream(nullptr) or
-setFile(nullptr), m_f or m_s will, respectively, still contain a pointer
-to the previous member, which is used when one calls setFile() or
-setStream() again, since these methods will call flush().
-
-For example, a program doing
-
-   s.setFile(f1);
-   s.setStream(nullptr);
-   fclose(f1);
-   s.setFile(f2);
-
-will call fwrite(f1, ...). This pattern can be observed in many parts of
-Doxygen, so fixing it in TextStream itself by always zeroing the other
-pointer is the simplest fix.
