I have the same problem as #766769 I am raising this as a new bug though because: abrt detects it as the bug mentioned above ( https://retrace.fedoraproject.org/faf/reports/8118/ ) I can't reopen the old one I am on x86_64 ( the bug appears to specify i686 I am on FC17 (which isn't mentioned in the bug) My version of virt-manager is 0.9.4-1.fc17.noarch, which is newer than the version mentioned in the other bug.
virt-manager is not related to this issue (I don't know why abrt says so). * At least full backtrace is needed to investigate this issue. Would you gain the information from core file (perhaps located uder ~/.abrt/spool)? * Also the line 1230 in maze.c is really complicated. Can you take the real value of st, st->maze *(st->maze), ss, *ss? * And do you have some idea about when this issue occurred? Currently I don't have x86_64 machine so I cannot analyze your core file...
Yes, I was very surprised to see that the bug had virt-manager for the resolution. It didn't seem that it could be related, but who knows. I think abrt correctly identifies it as bug 766769, but maybe the resolution given in that bug is wrong. I only have one thing under ~/.cache/abrt/spool/ : ccpp-2012-10-17-19:00:08-1151 $ cat core_backtrace 299dc351ed4bf6ab068452328b2873f27205ea34 0x4942 - /usr/libexec/xscreensaver/maze bfed8be0a2dc26612a3c3c6bdb3971c058100fa4 299dc351ed4bf6ab068452328b2873f27205ea34 0x297d - /usr/libexec/xscreensaver/maze f914286b73387cc3323a5b47e4eb98189d60d713 df54c88ec91ef43fa6225e34d46e847dd76e1348 0x21735 __libc_start_main /lib64/libc.so.6 075acda5d3230e115cf7c88597eaba416bdaa6bb 299dc351ed4bf6ab068452328b2873f27205ea34 0x326d - /usr/libexec/xscreensaver/maze - $ cat var_log_messages Oct 17 19:00:08 4gbl10280 kernel: [207476.582494] maze[1151]: segfault at 7ff96db588e0 ip 0000000000404942 sp 00007fffc6c62b60 error 4 in maze[400000+17000] Oct 17 19:00:09 4gbl10280 abrt[1238]: Saved core dump of pid 1151 (/usr/libexec/xscreensaver/maze) to /var/spool/abrt/ccpp-2012-10-17-19:00:08-1151 (20742144 bytes) $ cat cmdline maze -root This issue occurs pretty much randomly, but not that often. I will lock my screen (either to go to a meeting, lunch, or home), and when I come back, it is unlocked, which is obviously not a great situation. I am running XFCE. I have to run xscreensaver & after it has crashed to get it locking again. I might write a little script in cron to start it if it isn't already running - that way, there'll only be a little window where my machine is unlocked until the bug is fixed. Let me know if you need anything else.
(gdb) print ss->x $3 = -1 (gdb) print ss->y $4 = 22 ss->maze produces a lot of output - I can send it if you need it.
(In reply to comment #3) > (gdb) print ss->x > $3 = -1 This is difinitely an issue. Would you tell also me the following value? * ss->i * dir * st->path[ss->i].y * st->path[ss->i].x * st->path[ss->i -1].y * st->path[ss->i -1].x * st->maze[st->path[ss->i].x][st->path[ss->i].y] * st->maze[st->path[ss->i].x + 1][st->path[ss->i].y] * st->maze[st->path[ss->i].x - 1][st->path[ss->i].y] * st->maze[st->path[ss->i].x][st->path[ss->i].y + 1] * st->maze[st->path[ss->i].x][st->path[ss->i].y - 1] Some values may be invalid.
(In reply to comment #3) > ss->maze produces a lot of output - I can send it if you need it. For now I want to see the value in comment 4. If some other values are needed, I will ask you again.
Arrrgh, I've absentmindedly clicked Delete in the abrt tool, and have lost the coredump. :/ I'll wait for the next crash (shouldn't be too long - a few days), and I'll give you the values from that one. Thanks for your help on this, by the way.
