random crashes when scrolling map

Hi,

navit randomly crashes when scrolling the map over big distances. It seems, in function event_glib_call_timeout_single in event_glib.c sometimes an invalid timerevent gets removed.

Thank you for your report. Could you provide some more details?

• On what OS/platform does this happen?
• Which graphics plugin do you use? (<graphics type="XXX"/> in navit.xml)
• Which SVN/Git version did you use? You can see that in the "About" menu.
• Could you run the program under gdb and provide a backtrace of the crash?

Also, could you provide a way to reproduce the problem? Ideally, upload the navit.xml and the map file somewhere (do not attach it here, as it will probably be too big).

It happens at least on Debian armhf and amd64 with qt_painter and gtk_drawing_area, but I forgot to mention, only if the device has a gps fix. I'm always using the latest svn/git version, but the problem is there for months.

The strange thing is, with gdb the problem isn't reproducable. And another one: On every there are different error messages (from glibc). The most common error message is "smallbin double linked list corrupted".

My config is split into several parts: ​http://linux.bierrommel.de/navit/etc/navit.xml ​http://linux.bierrommel.de/navit/navit.xml ​http://linux.bierrommel.de/navit/gui.xml ​http://linux.bierrommel.de/navit/osm.xml ​http://linux.bierrommel.de/navit/routing.xml

With the information available I have not been able to reproduce the problem. Since this ticket is quite old, I'm closing it.

Feel free to reopen if you can provide more information. In particular, a backtrace would be helpful. If you cannot reproduce the problem runnign under gdb, you can enable core files with the command "ulimit -c unlimited". Then Navit will leave behind a corefile if it crashes, which you can analyse with gdb after the crash.
