[marcuscom] gnome 2.28 + linux apps = SIGSEGV ?

[Boris Samorodov]

Hello List,

I faced a problem with 9-CURRENT and 8-STABLE:
http://lists.freebsd.org/pipermail/freebsd-current/2009-November/013061.html

Both systems use gnome-2.28 from marcuscom. Can anybody use
acroread8 with gnome-2.28? (I'm not sure but seems that skype
and linux-realplayer get SIGSEGV as well.) Other 8-STABLE
system with gnome from current ports tree works fine.

Interesting.... I can't run linux-opera in MC either. At first, I thought  
it might be related w/ security.bsd.map_at_zero and I didn't bother to try  
it (by either update RELENG_8 w/ fixes or try this sysctl).

Until your email.... Makes me think that it might be related w/  
print/freetype2, because of fontconfig is showing up in your ktrace? Try  
to downgrade the freetype2 and see if it helps? It's only thing that I can  
think of what change in MC related w/ font stuff, I will need to check in  
MC more. In the past, there was problem with linux apps when Linux and  
FreeBSD have different version of fontconfig (cache stuff) at the same.  
But this isn't in case as fontconfig isn't update or change in MC.

Cheers,
Mezz

Jeremy, good shot! It was fontconfig. I downgraded it to 2.6.0 and
acroread now works.

Is it? The version from MC was 2.7.3.

Well, in any case, the kernel should not do SIGSEGV, isn't it?

Great, all we need to figure a solution now on a right target. ;-)

Oops, I was looked at the wrong terminal window (only knew about freetype2  
change but not fontconfig). :-) Yeah, MC does has fontconfig change. Must  
be cache issue just like before. Let me try to dig in the archives and see  
if I can find old thread about fontconfig as my memory is pretty fuzzy  
with this. Not sure if it's possible to use Linux's fc-cache to have  
seperate cache or have to force Linux's fontconfig to be upgraded.

I just remember that I am a person that reported this bug when someone  
updated fontconfig.

No idea, I am no expert and no knowledge about what kernel should and  
shouldn't.

Cheers,
Mezz

I can't find old thread in the archive. I have taken a look at your kdump  
again and I think it's more like update linux-fontconfig is a better  
solution.

If there is not a new feature since the last time the issue came up, we
only have the option to update the linux-fontconfig.

Bye,

Hi, there seems to be a trick to get linux acroread running. Just use
sysctl(8) to turn 'security.bsd.map_at_zero' from '0' to '1'. It works
for me, at least. I'm using 8.0-RC2 amd64.

good luck.

I think that the latest 8-STABLE doesn't need this trick. But my
problem was with incompatible fontconfig from marcuscom gnome-2.28.

Does this still happen with fontconfig 2.8.0?  This new version uses a
new cache version which should be parallel-installable next to earlier
versions.

I didn't have a chance to test it. Seems that the next week I won't
have time either. But thanks for the headsup, I'll try when have
some spare time.

I think it has been solved w/ that fontconfig 2.8.0. I am able to run  
linux-opera now.
