Hi!

I'm not sure, but I've been struggling with this bug:

media-libs/mesa-13.0.0_rc2: libGL crashes on hardened AMD64
https://bugs.gentoo.org/show_bug.cgi?id=598593

( my duplicate is at:
=www-client/firefox-49.0 segfaults with >=media-libs/mesa-13.0.0_rc1 on
	>=4.4.8-hardened-r1
https://bugs.gentoo.org/show_bug.cgi?id=598700
)

and it looks like (I had better show you the standard output when
starting firefox 49.0 on plain 4.8.3 kernel:

ATTENTION: default value of option force_s3tc_enable overridden by
environment.
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings
will not be saved or shared with other applications.
1478449652215	addons.productaddons	WARN	Failed downloading XML,
status: 0, reason: error

(firefox:5208): GLib-GIO-CRITICAL **: g_loadable_icon_load: assertion
'G_IS_LOADABLE_ICON (icon)' failed

and a few more lines to that effect.

After some ducking for info I see that:
https://en.wikipedia.org/wiki/S3_Texture_Compression
is mostly used for games (and I'm not a gamer.)

But it looks like, apart from mesa alleged fix (see in the bug report)
not having propagated to us, [it looks like] that s3tc functionality is
missing for my Firefox to behave...

There have been various tips in the various distro flavors about
enabling s3tc, but I couldn't get it to work in Gentoo.
Such as after emerging:

# emerge media-libs/libtxc_dxtn

and issuing:

$ force_s3tc_enable=true firefox

That still got me the line:

ATTENTION: default value of option force_s3tc_enable overridden by
environment.

Also, the useflag:

https://packages.gentoo.org/useflags/s3tc

only has:

app-emulation/wine

as sole customer at this time...

I wasn't sure this was a post for the bug report that I linked to above, so I'm asking here on the users list.

Anyone has any more clue about this issue?

Regards!
