Report overlaps related sigsegv and assertion 10.5 failures




      Elena Stepanova:
      'Here is a very dirty MTR test case. If you put it into the galera suite in 10.5 and run with the standard options, it should fail, either with sigsegv (signal 11) or with a debug assertion failure, both somewhere in handler::ha_check_overlaps in Galera replication . Could you please clean it up – remove all garbage, comments, get rid of disable_abort_on_error, rename tables and columns, organize in a proper way, etc – make it look like a decent MTR test case – and report the bug for Galera and Versioned tables components together?
      It may look like a zillion bugs in overlaps, report it anyway, unless you find out it's unrelated to Galera. I'm not sure those fixes will cover Galera replication.
      Please try to get both sigsegv and assertion failure and put both into the bug report. If you can't get the assertion failure, try a single-node "cluster" (galera suite is a 2-node cluster). Many things are different there.
