Bug 182625

I would be very interested in resolution of this error as well.
There is a lengthy discussion on the debian list; there seems to be some
indication that some of the nvidia stuff causes this problem.

Any reference(s)?

Of course, if anyone experiencing this problem is *not* using FC's
standard/open-source drivers, we ask that you try to reproduce the problem only
using them.

Although I do have an nvidia card, I'm using FC's open source drivers. 
Moreover, at no time in the history of this machine I've ever installed the 
proprietary nvidia driver, or any of the other stuff that comes with it. 
The crash described happens with the drivers that come with FC4.

Actually, I don't use propriety nvidia drivers either. 
It potentially looks like an upstream error in one of the libraries?

Interesting reading, but unfortunately, about 90% useless... as they were so
quick to blame nvidia drivers, which we've already ruled out.  

Looks like until this is fixed (upstream most likely), we'll have to pull the
broken x86_64 builds.

BTW, anyone able to confirm this on fc5(devel)/x86_64?

> BTW, anyone able to confirm this on fc5(devel)/x86_64? 
I've installed both FC5/i386 and FC5/x86_64 as QEMU guests. Same outcome: 
geomview works under FC5/i386 and crashes on startup on FC5/x86_64. 
 
By the way, QEMU is supposedly capable of running (albeit slowly) x86_64 
guests on a i686 host, so if you have a few GB of disk space to spare, you may 
want to consider using it to test 64-bit builds of your packages.

PS. The fact that QEMU's virtual video card is a Cirrus Logic GD5446 dispels 
any lingering notion that this has anything to do with nVidia cards. 

I have wasted some time on running a debug on both i386 and x86_64. The error is
caused by (what looks like) an error (corrupted instruction) in geomviews
instruction queue during initialisation--grepping through some files, I see that
that geomview makes some 32 bit assumptions in OOGL magic numbers etc. I
conclude that geomview is probably not 64 bit safe, but don't have the time to
waste to trace the problem in more detail.

I can confirm.

My machine is a x86_64 under FC-5.
geomview-1.8.2-0.2.cvs20040221.fc5.3
NVIDIA card, but with free drivers, not accelerated.

Looks like we'll have to pull the x86_64 build(s) from the repo.

Any chance to fix this bug?

AFAICT, no one (including upstream) is working on this.

I'll scounge around in the debian patches... they claim to have fixed the 
problem.

I have a QEMU image of Debian testing/amd64, and it definitely doesn't look 
like they have.

Debian bug is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314988 but I 
cannot see any patch for it.

The geomview-users list was abuzz recently, and it appears that geomview cvs
works.  Can someone test build this on their x86_64 box to see if to works for
you on x86_64?

YES!!! It compiles and run correctly. I am very happy to eventually have a 
working version of geomview on my laptop (I need it for my work)!

Warning: even if it works, rpmlint is *very* verbose about the compiled 
packages. Do you want me to copy its results?

> YES!!! It compiles and run correctly

Great, I'll get to work pushing this out to Extras.  fc6/devel branch is already
done... I'll get to FC-5/FC-4 probably on Monday

> Warning: even if it works, rpmlint is *very* verbose...

I'll check that, thanks.
