Created attachment 823703 [details] emerge_info Starting with firefox 105.0.2 the build fails in the PGO phase. This is always reproducible with X and wayland, I suspect this is related to xdg-desktop-portal as journal shows dbus activations and fuser mounts. The build log isnt very verbose however: $ journalctl -e ... org.freedesktop.portal.Documents[266084]: fusermount3: mount failed: Operation not permitted org.freedesktop.portal.Documents[266073]: error: fuse init failed: Can't mount path /var/tmp/portage/www-client/firefox-105.0.2/temp/run/doc dbus-daemon[266065]: [session uid=250 pid=29004] Activating service name='org.freedesktop.impl.portal.desktop.gtk' requested by ':1.1' (uid=250 pid=29009 comm="/usr/libexec/xdg-desktop-portal") dbus-daemon[266065]: [session uid=250 pid=29004] Successfully activated service 'org.freedesktop.impl.portal.desktop.gtk' dbus-daemon[266065]: [session uid=250 pid=29004] Activating service name='org.freedesktop.impl.portal.desktop.kde' requested by ':1.1' (uid=250 pid=29009 comm="/usr/libexec/xdg-desktop-portal") dbus-daemon[266065]: [session uid=250 pid=29004] Successfully activated service 'org.freedesktop.impl.portal.desktop.kde' dbus-daemon[266065]: [session uid=250 pid=29004] Activating service name='org.freedesktop.secrets' requested by ':1.1' (uid=250 pid=29009 comm="/usr/libexec/xdg-desktop-portal") gnome-keyring-daemon[266097]: couldn't access control socket: /var/tmp/portage/www-client/firefox-105.0.2/temp/run/keyring/control: No such file or directory gnome-keyring-daemon[266097]: discover_other_daemon: 0 gnome-keyring-d[266097]: couldn't access control socket: /var/tmp/portage/www-client/firefox-105.0.2/temp/run/keyring/control: No such file or directory dbus-daemon[266065]: [session uid=250 pid=29004] Successfully activated service 'org.freedesktop.secrets' dbus-daemon[266065]: [session uid=250 pid=29004] Successfully activated service 'org.freedesktop.portal.Desktop' systemd[1]: Started Process Core Dump (PID 266178/UID 0). systemd-coredump[266179]: Resource limits disable core dumping for process 266011 (firefox). systemd-coredump[266179]: Process 266011 (firefox) of user 250 dumped core. systemd[1]: systemd-coredump@99-266178-0.service: Deactivated successfully. systemd[1]: Started Process Core Dump (PID 266189/UID 0). systemd-coredump[266190]: Resource limits disable core dumping for process 266010 (python). systemd-coredump[266190]: Process 266010 (python) of user 250 dumped core. systemd[1]: systemd-coredump@100-266189-0.service: Deactivated successfully. ...

Always try without (s)ccache first if build fails. If you have these "rather aggressive" flags enabled system-wide it could also be that some of your system libraries are broken, or not compatible with Firefox. If the build fails after disabling ccache, try to also disable the system-* use flags. Unfortunately there's not much we can do about ccache issues.
Disabling ccache for www-client/firefox indeed fixed the issue. Thanks for the quick response and sorry for the noise, I will deactive ccache and all system-* USE flags next time before filing a bug.
Glad to hear it worked!
