Vlc segfaults (no fluidsynth installed)

I've researched into why vlc is broken as of recently with its latest update. I also have the testing repo enabled if that helps. I try to run vlc but I get

/tmp/alpm_MmFPEE/.INSTALL: line 1:  7257 Segmentation fault      (core dumped) usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins

I also tried to compile vlc-git, but i also get:

  GEN      ../modules/plugins.dat
/bin/sh: line 4: 20892 Segmentation fault      (core dumped) ./vlc-cache-gen ../modules

I also did not have fluidsynth installed when doing this. I'm not sure what plugins are causing this, here's the list of recommended dependencies installed:

Re: Vlc segfaults (no fluidsynth installed)

I had the same problem today (My Dragon Player was also affected). After downgrading my nvidia driver (back to 346.59-1) VLC worked again.

If you're on an intel CPU, make sure you've installed and configured the microcode updates.

Thanks, I'll try this when I get home and edit with results. Also I'm using nvidia.

Re: Vlc segfaults (no fluidsynth installed)

Come on, people. Downgrading is not the solution, the microcode update is. Haswell CPUs and early Broadwell CPUs have a bug.

Microcode update worked for me, thx.

Re: Vlc segfaults (no fluidsynth installed)

Come on, people. Downgrading is not the solution, the microcode update is. Haswell CPUs and early Broadwell CPUs have a bug.

I installed the microcode update and it still segfaults when trying to do

/usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins

There shouldn't be any problems with how I installed the microcode update either since the initrd line in my grub.cfg contains the update.

initrd  /boot/intel-ucode.img /boot/initramfs-linux.img

Funnily enough, I remember having this problem a while ago and installing intel-ucode fixed it. Well, now it does not. Any ideas?

Here's some stuff that might be useful:

Anyone know what this could mean? I assume it does have something to do with the Nvidia driver after all.

Re: Vlc segfaults (no fluidsynth installed)

Oh, nevermind, it fixed itself it seems. Must have been some update. VLC works again for me.
