Description (last modified by slyfox) (diff)

Reported by dkostousov on mc-dev@…

To reproduce error:

  1. gen newest glibc (I think 2.9+)
  2. create file in ~/temp/ with name
    videoplayback?ip=0.0.0.0&sparams=id,expire,ip,ipbits,itag,burst,factor&itag=22&ipbits=0&signature=8C3C490979492A3384FBC602C8E9E581FCD3303B.5B842F8BA40ED17BD402F8ADF4801B15D2A5B7E8&sver=3&expire=1249488000&key=yt1&factor=1.25&burst=40&id=efab704b0e6836cb
    
  1. start mc and go there

Result will depend on your luck. Sometimes mc SIGSEGVs, sometimes glibc detects heap corruption.
