xine_init() causes segfault in libselinux

[Vikram Noel Ambrose <noel.ambrose@gmail.com>]

Hello Everyone,

I've managed to find a repeatable segfault scenario with some very basic 
libxine code.

libxine if anyone doesnt know is a very popular audio backend for many 
userspace applications in KDE and Gnome.

Here is the code: http://en.pastebin.ca/1376316

The code basically opens a file stream with no Audio or Video drivers, 
and just reads the meta data from the file (title information), and then 
quits.

A gdb backtrace and valgrind have led me to believe there is a fault in 
libselinux.

Though this could very possibly be a fault in libxine, I'd have thought 
libselinux would be more resilient to such issues. Especially since 
glibc didnt complain.

If you would like to run this test code, simply install xine-lib-devel 
and then compile the test program.

$ gcc -lxine -g test.c
$ ./a.out

I'm using an up-to-date FC10 x86_64 installation. 
2.6.27.19-170.2.35.fc10.x86_64
