Question 190.36: Segmentation fault

190.36 on x86_64:

Backtrace:
0: /usr/bin/X (xorg_backtrace+0x28) [0x49e4d8]
1: /usr/bin/X (0x400000+0x61859) [0x461859]
2: /lib64/libpthread.so.0 (0x7f97dc956000+0xf320) [0x7f97dc965320]
3: /usr/lib64/xorg/modules/drivers/nvidia_drv.so (0x7f97d6ceb000+0xa4872) [0x7f97d6d8f872]
4: /usr/lib64/xorg/modules/libwfb.so (wfbPadPixmap+0xbb) [0x7f97d68bafab]
5: /usr/lib64/xorg/modules/libwfb.so (wfbValidateGC+0x301) [0x7f97d68bb321]

X crashes every 20, 30 min, under normal usage, on the same wfbPadPixmap.

I can reproduce easily, realiably:
- KDE4 -> konsole -> nvidia-settings -> click on "cursor shadow": crashes 100% of time.

Anyone else seeing this?

Default Re: 190.36: Segmentation fault

I tried it but it did not segfault.

Fedora 10+, KDE-4.3.1, T61, NVS140M.
I have Option "UseEvents" "False" in xorg.conf.

It may be related to some desktop effect you have turned on.

Default Re: 190.36: Segmentation fault

I have tried, but can't trigger seg fault.
I'm in a Debian Sid (unstable), kernel vanilla 2.6.31.1 in a HP Pavillion dv6000 series and a GeForce 8400M GS.
Running 190.36 for 64bits.

I'm at loss... still crashes with UseEvents false.
Disabling compositing does not help.
I've tried AllowSHMPixmaps 0 also, but no luck...

What is the output of ldd /usr/lib64/xorg/modules/libwfb.so?

Code:
[root@localhost]# ldd /usr/lib64/xorg/modules/libwfb.so
linux-vdso.so.1 =>  (0x00007fff5b1a1000)
libaudit.so.1 => /lib64/libaudit.so.1 (0x00007faf9b59b000)
libselinux.so.1 => /lib64/libselinux.so.1 (0x00007faf9b37d000)

libpthread.so.0 => /lib64/libpthread.so.0 (0x00007faf9a74e000)
libwfb.so seems to be related to the crashes: with an old libwfb.so from X 1.6.4,
everything works fine!

Default Re: 190.36: Segmentation fault

I am running a Quad Core 9400 with an Nvidia Gforce 9800GTX+ and Ubuntu Ultimate Edition 2.3. I have had no problems. I output DVI to HDMI on a Sony 50" HDTV at 1920x1080. The biggest advantage I have found with 190.36 is that it finally gives me the ability to correct for Overscan and allow me to Shrink the Display so that it fits within the boundaries of my HDTV screen. I have not detected any other undesirable side effects.
