--- Comment #16 from Matthias Pfafferodt 2010-11-28 20:25:50 UTC ---
I did hope to prevent the bug by repartition and reformat my hard disk. But the
bug is still there. Before the bug, I did compile freeciv trunk and run it
which resulted in a segfault (known bug). I did create a core dump and the
following log output is the result. Compared to the last bugs, these one has
not crashed the system till now ...
