Bugzilla Bug 31235

SDL 1.2.6-r1 fails when starting orbital-eunuchs-sniper, frozen-bubble or
tuxracer in fullscreen mode. o-e-s and f-b do work in windowed modes; however,
when you try to start a game from the frozen-bubble menu screen, it exits with
the message "Illegal Instruction".

I'm using XFree 4.3 with the hardware-accelerated ATI drivers (i.e. ati-drivers
package) on an M9 (Radeon Mobility 9000). The problem was fixed by downgrading
with 'emerge "=libsdl-1.2.5-r2"'.

orbital-eunuchs-sniper was also jerky and prone to segfaulting even in windowed
mode prior to downgrading.

Reproducible: Always
Steps to Reproduce:
1. Emerge libsdl-1.2.6-r1
2. Emerge orbital-eunuchs-sniper, frozen-bubble, or tuxracer
3. Try to run one of the above in fullscreen mode
Actual Results:  
Program exits with a segfault

Expected Results:  
Er.. no crash :)

I've had the same problem with dosbox and abuse.
I get segfault trying to do fulll screen.

I'm using voodoo 3 3000 card, latest stable xfree - 4.3.0-r3,  and xfree-drm
4.3.0-r6.

could you try this ?
export EXTRA_ECONF="--disable-nasm"
emerge libsdl

Doesn't work for me.
I'm getting "Fatal signal: Segmentation Fault (SDL Parachute Deployed)" trying
to do fullscreen.

I had a reason to believe that export EXTRA_ECONF="--disable-nasm" had no
effect as I saw the configure script saying it detected nasm.

I made a change to the ebuild itself, and put the --disable-nasm in the econf
and removed the `use_enable x86 nasm` line.

But that didn't help as well, and the same result persists.

I had the same exact problem as you. To fix it, please make sure you have
more modeline definitions (ie 1024x768, 800x600, and 640x480) in your /etc/XF66Config
file.

Restart X, and hopefully this will fix your issue.

Adding extra modelines did stop the segfaulting, but tuxracer and o-e-s are
INCREDIBLY jerky (and run perfecly using 1.2.5-r2), and the problem of being
unable to start games in frozen-bubble also persists. So although I can now
get fullscreen apps to at least run with 1.2.6, until the other two issues
are cleared up, I'll stick to 1.2.5...

export EXTRA_ECONF="--disable-nasm" doesn't fix the jerkiness or frozen-bubble
problems I'm having.

No segfaults after adding other modelines as well.

Try libsdl-1.2.6-r2.ebuild and see if that works better for you please.

Pretty sure this is fixed with libsdl-1.2.6-r2.ebuild.
