I am so sorry, to bring this up again:
After last time we did need to do a point in time recovery a few transactions before the fatal stuff, it seems to be we are stuck at the same point:
As soon as we now try to get into db_online the evil transaction seems to be read from the log
Rst 968 redo transactions readable and 32 redo tasks available.
Restart recovering log from log_volume from IOSeq: '71017143'
Log normal end of log found at off 764391 lastseq 71018647.
Log last-redo-read empty errlist#3245:TR973675497(7)[71018647]@764391.864'Commit':20140607:164721
DBSTATE Caught signal 11(SIGSEGV)
COREHAND ABORTING due to signal 11
So again now way to drop the bad Index or start the DB ...
