This is possibly in db5.3 then.

Cannot access memory at address 0xe60 I don’t have much ideas how to go further because the code paths are really hard to follow. I also am not sure it’s in db5.3 any more, as libsasl2.so.2 isn’t linked against it… bye, //mirabilos -- <hecker> cool ein Ada Lovelace Google-Doodle. aber zum 197. Geburtstag? Hätten die nicht noch 3 Jahre warten können? <mirabilos> bis dahin gibts google nicht mehr <hecker> ja, könnte man meinen. wahrscheinlich ist der angekündigte welt- untergang aus dem maya-kalender die globale abschaltung von google ☺ und darum müssen die die doodles vorher noch raushauen
