Hello, the List. I run Debian Wheezy (testing) on amd64 and with a few packages from Sid (unstable), i.e. the kernel.
All GNUstep-based graphical apps fault with SIGSEGV ; if I try lets say AClock, I get: [ WITH libpixman-1-0 0.22.2-1 ] testr@valentin-laptop:~$ AClock Segmentation fault testr@valentin-laptop:~$ And dmesg says: AClock[28182]: segfault at 8 ip 00007f06f8208c5e sp 00007fff532feeb0 error 4 in libpixman-1.so.0.22.2[7f06f81d6000+6f000] [/ WITH libpixman-1-0 0.22.2-1 ] [ WITH libpixman-1-0 0.23.2-1 ] testr@valentin-laptop:~$ AClock Segmentation fault testr@valentin-laptop:~$ AClock[29355]: segfault at 8 ip 00007f40357dfac3 sp 00007fffb565e840 error 4 in libpixman-1.so.0.23.2[7f40357ab000+73000] [/ WITH libpixman-1-0 0.23.2-1 ] But this bug happens with all GNUstep-based graphical apps. I've not been able to install GNUstep from experimental. I hesitate to file a bug report on Debian BTS because one can suspect the bug be in "gnustep-back0.18-cairo", "libcairo2", or "libpixman-1-0" for example. I've made traces of AClock (aclock.app package) using 'strace' and 'strace' tools, and I've made both partial and full core dumps. Here follows the listing of my core files I can upload somewhere upon request. testr@valentin-laptop:~$ ls -l core_AClock\=aclock.app_* -r-------- 1 testr testr 8708096 18 août 17:04 core_AClock=aclock.app_DEFAULT_libpixman_0.22.2-1 -r--r--r-- 1 testr testr 1309463 18 août 17:12 core_AClock=aclock.app_DEFAULT_libpixman_0.22.2-1.tar.bz2 -r-------- 1 testr testr 8744960 18 août 17:07 core_AClock=aclock.app_DEFAULT_libpixman_0.23.2-1 -r--r--r-- 1 testr testr 1297619 18 août 17:12 core_AClock=aclock.app_DEFAULT_libpixman_0.23.2-1.tar.bz2 -r-------- 1 testr testr 141176832 18 août 17:01 core_AClock=aclock.app_FULL_libpixman_0.22.2-1 -r--r--r-- 1 testr testr 10614028 18 août 17:12 core_AClock=aclock.app_FULL_libpixman_0.22.2-1.tar.bz2 -r-------- 1 testr testr 141225984 18 août 16:56 core_AClock=aclock.app_FULL_libpixman_0.23.2-1 -r--r--r-- 1 testr testr 10582652 18 août 17:12 core_AClock=aclock.app_FULL_libpixman_0.23.2-1.tar.bz2 testr@valentin-laptop:~$ Are you affected too by tis bug ? Please, tell me what I can do to help sort this problem out. You can find the "ltrace" trace in appendix. I can't join the "strace" trace nor publish it on paste.debian.org because of its size. I you want the "strace" trace or any of the 4 aforementioned core dumps, please ask me them directly at : vecu.boss...@gmail.com Sincerely, Valentin QUEQUET APPENDIX: testr@valentin-laptop:~$ cat AClock.ltrace.txt __libc_start_main(0x401320, 1, 0x7fffeacd43e8, 0x407340, 0x407330 <unfinished ...> __objc_exec_class(0x60e3c0, 0x7fffeacd43e8, 0x7fffeacd43f8, 0, 0x7fc5a3cf6320) = 0 __objc_exec_class(0x60bbc0, 0, 0x1182060, 0, 0x1229890) = 0 __objc_exec_class(0x609640, 0, 0x1182060, 0, 0x121de70) = 0 objc_get_class(0x407424, 0x7fffeacd43e8, 0x7fffeacd43f8, 0, 116) = 0x7fc5a4b9cea0 objc_msg_lookup(0x7fc5a4b9cea0, 0x6095e0, 0x407434, 0x407424, 108) = 0x7fc5a4760910 objc_get_class(0x407436, 272, 0, 0x7fc5a45c82a0, 0x7fc5a3cf6fc8) = 0x7fc5a52b0860 objc_msg_lookup(0x7fc5a52b0860, 0x6095f0, 0x407442, 0x407436, 110) = 0x7fc5a4e45b10 objc_msg_lookup(0x12def70, 0x609600, 0, 0x1700000001, 1) = 0x7fc5a4e460e0 --- SIGSEGV (Segmentation fault) --- +++ killed by SIGSEGV +++ testr@valentin-laptop:~$ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
