[gentoo-hardened] Xorg fails to fork therefore cannot invoke xkbcomp

[atoth]

Xorg.log
(**) Option "xkb_rules" "evdev"
(**) Option "xkb_model" "evdev"
(**) Option "xkb_layout" "hu,us"
(**) Option "xkb_variant" "standard"
(**) Option "xkb_options" "grp:shift_toggle,compose:ralt"
(EE) XKB: Could not invoke xkbcomp
(EE) XKB: Couldn't compile keymap
(WW) Couldn't load XKB keymap, falling back to pre-XKB keymap

grsec.log
grsec: (root:U:/usr/bin/Xorg) failed fork with errno -12 by
/usr/bin/Xorg[X:pid] uid/euid:0/0 gid/egid:0/0, parent
/usr/sbin/gdm-binary[gdm:pid] uid/euid:0/0 gid/egid:0/0

Result: wrong keyboard layout, compose key don't work, I cannot even
switch to a terminal.

Any clues how to solve it?

I think I experienced a similar problem some time ago.
Changing the pax flags on /usr/bin/Xorg worked for me.

Pax somehow prevented Xorg from compiling a new keymap.

Type "paxctl -pemrxs /usr/bin/Xorg", which should disable all
restrictions and try it again.

If I recall correctly, I could reset the flags to their default values
(paxctl -zxe /usr/bin/Xorg) after Xorg started with the correct keymap.

I hope this helps.
