Seems to be the old problem still, probably a synchronisation error. Happens on machine with many cores (>16). I'll try to figure out what's wrong ASAP.

Error happened when the buffer grew beyond the starting size (60 KB) and decoding was restarted after a while. In that case the buffer was shrunk to these 60 KB, causing buffer access beyond these 60 KB to fail.

Should be fixed now :)
