Description Alexander Krylov 2017-05-22 16:56:06 CEST 
Description of problem:
Latest 'tainted' VLC segfaults upon execution...

[username@localhost ~]$ vlc
VLC media player 2.2.5.1 Umbrella (revision 2.2.5.1-14-g05b653355c)
Segmentation fault

Deleting VLC settings dir (~/.config/vlc) makes no difference.

Funny thing:
gdb vlc
(gdb) r

Spawns a working VLC process.


Steps to Reproduce:
1. Execute vlc or cvlc command with terminal.

New gdb output with correct version of glibc debug package.
Comment 3 Alexander Krylov 2017-05-22 18:39:06 CEST 
Solved with a weird workaround...
Since gdb and strace both can spawn a working VLC process, problem was solved with:

[root@localhost ~]# strace /usr/lib64/vlc/vlc-cache-gen -f /usr/lib64/vlc/plugins/

Running above command without strace also initially lead to segmentation fault.
Now VLC runs and works fine.
