VLC randomly crashing during streaming of udp/rtp, mpeg4 ts.

[Alant]

Centos4u2, vlc 0.8.4 and latest svn.

As I understand params of *memcpy* are incorrect, i tried to force using
memcpy and got the same crashes.
Here 3 backtraces.

Bump

I just came across this problem and reported it on the dev mailing list:
http://www.via.ecp.fr/via/ml/vlc-devel/ ... 00439.html

Note: interestingly, I'm also seeing this on CentOS 4.2 box

I found a bug, made fix for it, and send letter to dev maillist. Now vlc
works without crashes.
You can see my letter at
http://www.via.ecp.fr/via/ml/vlc-devel/ ... 00193.html

It's funny, that my fix was ignored by dev team.
