Hello Fabian,
can confirm that both variants are fixing the issue.
I would prefer the function level fix, but as there is already a change
to the build system that does exclusively apply to this file, I think
both are equally good.
(And when OCaml 4.02 enters Stretch we can try removing it
Hello Fabian,
your patch fixes the issue.
But I fear by using static we potentially introduce a race condition,
if there are any applications encoding in two threads?
(May I ask if there are any reasons against __attribute__((aligned(0x20)))?)
Kind regards,

Hello Fabian,
after some more searching and testing here is my opinion on this issue:
- OCaml versions 4.01 (used in Jessie) and before are not doing stack
alignment on 16 byte boundaries [1].
- GCC does 16 byte stack alignment (at least when using SSE instructions)
at compile time.
- Now

But it did not help either. The packed gets ignored.

Description: Workaround to build libav for i586 with gcc 4.9.2 by avoiding memset

Hello,
sorry for the delay.
Yes, I would vote for getting these 3 changes into Jessie (if it is up
to me?).
This 3 changes should only affect the file:
/usr/lib/i386-linux-gnu/libavcodec.so.56.1.0
But I think most users today would use this version:
Hello hikaru,
(I have tried to split the browser issue into a different bug #783293.)
When libav is built with this 3 attached changes then vlc and mplayer2
are not crashing anymore.
This would need some more tests as I had only my qemu VM (which was way
too slow) with one video file inside.
Hello hikaru,
additional to the patch above it looks like there is also a

This kodi-14 stack is nearly equal to the stack of xbmc-13 when we call the

The difference starts in CWinSystemX11::SetFullScreen.

I was successful in creating a package for kodi from you git

Hello Bálint Réczey,
thanks for your fast response.
One thing I am uncomfortable with my proposal is, if it would affect
people using some low spec computer which are not able to decode fast
enough in software and not having vdpau at all.
