Comment 2 Mads Kiilerich 2011-06-28 13:05:14 UTC 
This seems to be a crash in the garbage collector. That can only be caused by memory corruption - either in hardware, Python, or the few C modules that is a part of Mercurial.

I assume it is the same machine as used in bug 716433?
Comment 3 Alexey Kuznetsov 2011-06-28 14:26:12 UTC 
yes

the same SLOW machine
Comment 4 Alexey Kuznetsov 2011-06-28 14:40:01 UTC 
just ran memtest.... it found some problems...

sory for you time, i ll stop post those reports.
Comment 5 Mads Kiilerich 2011-06-28 19:12:23 UTC 
ok, closing until we get some evidence of the same problem on other and more stable hardware.
