Looks like corruption of the malloc arena:

#0  0x08061bdb in ConfigItemTable::findItem(unsigned long) (this=0x824fc20, 
    id=1095258964) at config.cc:87
87                              if (n->ID == id) return n;
(gdb) print n
$1 = (ConfigItemNode *) 0x1
(gdb) print id
$2 = 1095258964
(gdb) print ConfigHashSize
$42 = 32
(gdb) print id % ConfigHashSize
$44 = 20
(gdb) print table[20]
$45 = (ConfigItemNode *) 0x852d330
(gdb) print *table[20]
$46 = {ID = 139026144, value = {number = 139584136, 
    string = 0x851e288 "\002"}, next = 0x1}

Since 'next' can, from inspection of the code, not be set to 1,
something seems to have stomped on parts of the memory involved.

I'll do some more digging.
