Does it also make sense to add -ggdb to the cactid rebuild to try and pinpoint the failure that way?

Nov 4 01:00:07 tux-mc page:c1114da0 flags:0x40000001 mapping:00000000 mapcount:0 count:0 Doesn't seem especially useful to me. Also, why is there still no symbol table available? I added the -ggdb, -nopie, nostrip flags as described in the links.
