I didn't do anything about it because I don't use MP3 (sorry) but some of the stuff could definitely be related to your overflow: Warning 5 warning C6385: Invalid data: accessing 'fSegments->s', the readable size is '20320' bytes, but '1572768' bytes might be read: Lines: 173, 174, 175, 177, 181, 182, 185, 189, 197, 198, 199, 200, 203, 205, 213, 215, 220, 222, 225, 226, 227, 228, 229, 230, 231, 234, 240, 244, 245, 246 mp3adu.cpp 246 Warning 6 warning C6246: Local declaration of 'bytesToZero' hides declaration of the same name in outer scope.
