Invariant failure when running aggregation against non-existent namespace

    • ALL
    • Hide
      db.runCommand({aggregate: 1});
      
      Show
      db.runCommand({aggregate: 1});

      Similar to SERVER-15642 and SERVER-15615, aggregate triggers an invariant failure when run against an invalid namespace. This bug only affects recent versions of 2.7.x.

      Program received signal SIGTRAP, Trace/breakpoint trap.
