Hi ALSA folks,
the alsactl segfault I've previously reported is still happening with
alsa-driver 1.0.0pre2 + alsa-* 1.0.0pre1 (installed from the sources).
- `alsactl store` or `alsactl restore` from the init process are segfaulting,
I can also see an oops in /var/log/message.
- when launching manually alsactl store or restore from userspace,
I don't get the segfault.
- even if crashing at startup, alsactl successfully restores the sound
settings
- the crash of alsactl at shutdown prevents it from saving the .state file
So I've saved it from normal userspace and next boot restored the
sound state :-)
I'm using a SuSE 8.1-based system (kernel 2.4.19, modutils 2.4.26), w/ many
upgrades from the sources. I used to upgrade alsa driver and other stuff from
0.9.3, and the problem only appeared since 0.9.7, IIRC.
Here are the excerpts from /var/log/message:

What info should I provide? Does anyone has a clue where's the problem is?
