Draft: InnoDB: Assertion failure in trx0i_s.cc line 1167 upon SELECT * FROM information_schema.innodb_trx

    XMLWordPrintable

    Details

      Description

      This failure was observed first by Sujatha.  It caused a SEGV on 10.5.8-enterprise.
      After adding a SELECT * FROM information_schema.innodb_trx to some RQG grammar
      I was able to hit the problem on some 10.6 development too.
