 Posted: Thu Jun 16, 2005 11:50 am Post subject: xine(64bit) glibc strange behavior, bug? |
 |
|
Hi@all
Everytime when i try to switch to fullscreen xine will crash with the message: | Quote: | *** glibc detected *** double free or corruption (!prev): 0x00000000015f1ee0 ***
Aborted
|
I've tried to install newer glibc(2.3.5) but the error is still the same. Can anyone give me a hint? I'm using gentoo 2005.0...

Are your CFLAGS to aggressive?
Try the standard CFLAGS and emerge glibc and xine new. |

This are my CFLAGS | Quote: | | -march=k8 -pipe -O2 -mfpmath=sse -msse2 -mmmx -m3dnow" |
I don't know, but I think they are not aggressive according to https://forums.gentoo.org/viewtopic-t-221361.html.
And yes I know that it is useless to put the -mfpmath=sse -msse2 -mmmx -m3dnow, but it also doesn't matter. But is there a difference between the k8 and amd64? Because in the Gentoo installation guide it says for amd64 users take --> k8 not amd64. |

The Gentoo amd64 technotes says:
| Code: | | The mmx, 3dnow, sse and sse2 USE flags are ignored on AMD64, since all AMD64 processors support those instruction sets. The are ignored because they enable 32bit assembly optimisation for some packages. |
It dosn't matter if you use march k8, athlon64 (not amd64) or opteron. I use -march=athlon64.

The technotes are talking about USE flags, not CFLAGS. 
Which version of xine-lib and xine-ui are you using, anyway? I don't have this issue, and these are the versions I'm running:
| Code: | [ebuild R ] media-libs/xine-lib-1.0.1-r3 +X -a52 -aac -aalib +alsa (-altivec) -arts -cle266 -debug -directfb +dvd -dxr3 -esd -fbcon -ffmpeg +flac -gnome -i8x0 -ipv6 -libcaca -mad +mng +nls -nvidia +opengl -oss +png +samba -sdl -speex -theora -v4l -vcd -vidix -vorbis (-win32codecs) -xinerama +xv -xvmc 0 kB
[ebuild R ] media-video/xine-ui-0.99.3-r1 +X -aalib -curl -libcaca -lirc +ncurses +nls +readline 2 kB |

My version for xine-lib is | Code: | | [ebuild R ] media-libs/xine-lib-1.0.1-r3 +X +a52 +aac +aalib +alsa (-altivec) -arts -cle266 -debug -directfb +dvd -dxr3 +esd -fbcon +ffmpeg +flac +gnome -i8x0 +ipv6 -libcaca +mad -mng +nls +nvidia +opengl +oss +png +samba +sdl -speex +theora +v4l +vcd +vidix +vorbis (-win32codecs) +xinerama +xv +xvmc 0 kB |
My version for xine-ui is | Code: | | [ebuild R ] media-video/xine-ui-0.99.3-r1 +X +aalib +curl -libcaca -lirc +ncurses +nls +readline 0 kB |
My version for glibc is | Code: | | [ebuild R ] sys-libs/glibc-2.3.5 -build -debug -erandom -hardened (-multilib) +nls -nomalloccheck -nptl -nptlonly -pic +userlocales 0 kB |
So I think all packages are the latest ones in portage... Can it be that it has something to do with the nvidia driver? There i use also the newest one | Code: | | [ebuild R ] media-video/nvidia-kernel-1.0.7664 0 kB |
Further information: It crashes always if i want to switch to fullscreen, no matter if I am playing a movie or not. But without fullscreen it works-->strange...
@Maedhros: Which version of glibc are you using?

Newer versions of glibc have better runtime error checking than did ealier versions. You can force the old behavior when you get one of these messages but my experience is that you will still get a seg fault error and the app will fail. It appears that for some reason you have some bad pointer code somewhere. But it could be in any of the libraries that are linked into the app. So for example it could be a problem in the nvidia or ffmpeg code . You might consider building xine-lib and xine-ui with debug turned on and run it in the debugger to see where is it actualy crashing.
I am currently runing xine-lib-1.0.1-r3 and xine-ui-0.9.23-r2 with no problems. My CFLAGS are -march=k8 -pipe -O2 |

| I changed my CFLAGS also to -march=k8 -pipe -O2 and compiled all the libs again, but with no solution. I think for the moment I just dont use xine and use instead mplayer which runs without any problems... Thanks for the help even it doesn't work right now. |

I played around little bit with xine and noticed that the error about the glibc doesn't appears when I double click xine to switch to fullscreen. After doing this it works all fine, but when I switch to fullscreen --> right click, press fullscreen it crashes with the error message i posted above. There is also a shortkey [f], when I switch to fullscreen with this one it also doesn't crash.
I want to ask if this error is reproducible by ohters, so that maybe there should be a bug report. |

That's the exact same behaviour as I'm experiencing.
right click to switch to full screen causes crash with the glibc error
trying to start the skin-downloader causes crash with the glibc error
double-clicking to switch to full screen works fine, same goes for using 'f'
glibc 2.3.4.20041102-r1
xine-ui 0.99.3
xine-lib 1.0-r2
using march=k8 -O2 -pipe |

| seems that it is really a bug, but I don't know where. It can be in xine-ui or xine-lib... But I think its strange, that not all users have this error... |
