  wrong. Patch by Torsten Hauska. Fixes #2710.
• mkvmerge: Matroska reader: fixed a segmentation fault when trying to read a
  file that uses header removal compression but no removed bytes are present
  in the track headers. Fixes #2687.
• mkvmerge: MPEG elementary stream parser: fixed an invalid memory access and
  use of uninitialized memory that could happen under certain
  circumstances. Fixes #2690.
• mkvmerge: RealMedia reader: fixed a division by zero when all audio
  time stamps were zero. Fixes #2689.
• mkvmerge: RealMedia reader: fixed an invalid memory access in the video
