Yea - should have thought to enable core dumps.

So it seems it's flash (even though I have an apparently functioning flashblock
enabled in seamonkey)

Core was generated by `/usr/lib/seamonkey-2.33.1/plugin-container
/usr/lib/mozilla/plugins/libflashpla'.

Should add - I've been playing around quite a bit with vdpau/uvd with mplayer,
mpv and ffmpeg - AFAICT I haven't managed to trigger this using them.

Looks like memory corruption. I don't suppose you can run this thing in
valgrind?

Seems I can't provoke this when running under valgrind.

There are thousands of other errors.

The version of flash I first reported with got marked as insecure, but the new
version still has the issue - well maybe it's seamonkey that has the issue as
plugin-containe is mentioned in the trap. 

Flash does still function OK and use vdpau after the trap.

When I get time I'll try Hg seamonkey and maybe firefox and see if it's still
there.

valgrind errors seamonkey.

After seeing these initially I updates a whole host of seamonkey dependencies
as listed in Beyond linux from scratch - glib, gtk, cairo and many more
dependencies of dependencies. Seamonkey is current release and rebuilt.

This trace is just starting the browser with a blank home page and closing.

I can't seem to build current Hg to test that.

vdpau trace including ff output

Testing with firefox now and seeing the same valgrind noise + flash behavior.

I ran with VDPAU_TRACE=1 and got a matching core as well. The timing of the
appearance of the core + the output indicate it crashes on

vdp_device_destroy

I can only see possible use-after-free bugs in seamonkey itself or the GTK
libraries in the valgrind output, nothing about libdrm_amdgpu.so.1.0.0 or even
the flash plugin. Maybe you need to pass --trace-children=yes to valgrind?

What I uploaded was as an example of the "other errors" I didn't even try to
crash that one.

I can't get a valgrind with the crash because (I think) it's so slow.

firefox will before playing anything decide the plugin has crashed - there is
no evidence that it has and not sign of amd grepping the near half a million
lines of output. I think it just has a timer on flash and I way too slow
running with valgrind.

I'll try harder tomorrow with seamonkey - it just seems to sit there not
starting the vid.

Without valgrind both will just play the vid without issue until I quit.

I haven't been using flash for a while.

Tried latest flash + seamonkey to test this, and I am not seeing it anymore.

It could be that seamonkey is now preventing it - with flash installed when I
go on a page with flash content seamonkey outputs -

Vector smash protection is enabled.
