Hi Lars,

hab nen neuen crasher (:-|) gefunden:

Program terminated with signal 10, Bus error.
#0  0x23bcc in call_out () at call_out.c:428
428             if (user->last_call_out != current_time)
(gdb) bt
#0  0x23bcc in call_out () at call_out.c:428
#1  0x21ac0 in backend () at backend.c:631
#2  0x7be38 in main (argc=-268438400, argv=0xeffff90c) at main.c:428

(gdb) frame 0
#0  0x23bcc in call_out () at call_out.c:428
428             if (user->last_call_out != current_time)
(gdb) print user
$1 = (wiz_list_t *) 0x20002
(gdb) print user->last_call_out
$2 = 1073717764
(gdb) print current_time
$3 = 1016737874

Sehr komisch - wenn alle variablen existieren, wieso crashts dann?

Viele Gruesse,

  Coogan.

Koennte dieser bug durch das condense_mapping() bei dev390 gefixt sein?
Falls nein, welche Werte willst Du noch wissen?

Viele Gruesse,

  Coogan.
