Yeah... that's what I thought it was. vlc does some interesting
work initializing codecs I think where it disguises runtime linker
issues, etc with pieces that tie into vlc. Not really happy about
that, but after the issue with zlib was identified 2~3 weeks ago, it
was easy to clean up...
The other issues with zlib are pretty well known, and the overall
upgrade as I and others mentioned a few weeks back is large as it's
use is pervasive in 3rd party software.
