...as reported by -fsanitize=address CppunitTest_hwpfilter_test_hwpfilter, where stack-local HStream stream from HwpReader::filter is still referenced from HStreamIODev in HStreamIODev::close HStreamIODev::~HStreamIODev HWPFile::~HWPFile HwpReader::~HwpReader which is only harmless because HStream::closeInput is a nop.
