Strange crash when exiting



  • This happens on Suse linux 13.2, and maybe it is a Suse reated problem.

    From time to time (maybe depending on the moon) my application crashes when exiting. The only thing I see in the debugger is:

    @(gdb) where
    #0 0x00007fffee066359 in ()
    #1 0x0000000000000000 in ()
    @
    Which is not helpful. When looking at the memory mapping of the process, I see
    @...
    7fffeb909000-7fffeb90a000 rw-p 00009000 09:02 19571475 /usr/lib64/libXrender.so.1.3.0
    7fffee2eb000-7fffef773000 r--s 00000000 09:02 9784329 /usr/share/icu/53.1/icudt53l.dat
    ...@
    so the crash happens somewhere between in the nowhere land :-(

    The crash is not easy to reproduce, once it happens and then for a day or so, I cannot reproduce and in the next morning it is happy here again, but just once.

    I already start my program this way, but that does not change anything.
    @gdb --eval-command=run --args ./myProgramm
    @

    Any idea?

    Hi,

    Shot in the dark but does it happen while your computer is idle ? When you wake it up ? Screen locked ?



  • The box is running 24/7 (used for distributed computing with boinc), no sleep mode or similar.

    It often happens when I start the program the first time on a day, before that I drink my coffee, read online news, mails and such, so the machine is already busy for a while.

    Also no screen lock (actually I just blank out the screen, I do not lock) while the program is running.
