Bugzilla Bug 71693

I get crashes involving the following message:
Segmentation Fault (SDL Parachute Deployed)
for the following games:
tuxracer
supertux
fish-fillet

Methinks this is a problem with SDL, but I don't know how best to investigate

Reproducible: Always
Steps to Reproduce:
1.emerge tuxracer supertux fish-fillet
2.try running each of the games
3.they all crash, specifically:

bash-2.05b$ tuxracer

try remerging all the sdl stuff on your system and the games with
CFLAGS="-pipe".
If that fixes things for you, try to isolate which package and cflags are
causing the problem.  Reopen this bug with more information after you've tried
that.

Changed CFLAGS to nothing but -pipe. Wiped all USE flags, except for USE="X gtk
gnome -alsa". Still same crashes. 

Tried it with USE="" and CFLAGS="". 

emerge sdl-gfx sdl-image sdl-mixer sdl-net sdl-sound sdl-ttf tuxracer supertux
fish-fillets

Everything still crashes on startup, just like before. Should I re-emerge some
packages lower down the build chain? What packages should I try reemerging?

What's the output of the command "groups" ?

reopen with more information.

Okay discovered the problem. I hadn't setup ALSA drivers properly. I ran
alsaconf, which failed due to the lack of /etc/alsa, then did "touch
/etc/alsa", then ran alsoconf again, setup my soundcard. Now everything works
fine, no more complaints about the old SDL parachute. I wish there would be a
more meaningful error message, like "no sound device found. Do you need to
configure your sound device?" The message about "SDL parachute deployed"
certainly doesn't help track down the real problem.
