Comment 3 for bug 1136432

I also may confirm this issue with lua.
I faced it trying to play a video from public web-cam.

===================

So from this back-trace I made an assumption that lua falls in segfault processing "/usr/lib/vlc/lua/meta/reader/filename.luac".
And indeed:

===================

So to reproduce this we need:
===================
1. Lua script (I'll attach it later as well): http://git.videolan.org/?p=vlc.git;a=blob_plain;f=share/lua/meta/reader/filename.lua;hb=HEAD
2. Compile script:
luac filename.lua
3. Run compiled lua script:
lua luac.out
===================

Also I noticed if lua-5.0 (/usr/bin/luac50) is used for compilation then lua-5.0 (/usr/bin/lua50) may as well correctly execute compiled script.

Lua 5.2 crashes the same way as 5.1 does.
===================
/usr/bin/lua5.2 -v
Lua 5.2.1 Copyright (C) 1994-2012 Lua.org, PUC-Rio
===================

So seems like regression introduced in 5.1 and still existing in 5.2.1
