FormatterToXML - assert() failed if buffering disabled

           Summary: FormatterToXML - assert() failed if buffering disabled
           Product: XalanC
           Version: 1.5
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: XalanC
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


following assertion failed if buffering == false (last FormatterToXML 
constructor param fBufferData), cuz m_charbuf is resized to a size >0 only if 
buffering is used.

XMLSupport/FormatterToXML.cpp (line 890):
void FormatterToXML::flushChars()
{
        assert(m_charBuf.size() > 0 && m_charBuf.size() >= m_pos);
        m_writer->write(&m_charBuf[0], 0, m_pos);
        m_pos = 0;
}
