      Failure text (identical for all three)

      include/master-slave.inc
      Bug in test case: '$SERVER_MYPORT_2' not initialized. Check the test's .cnf file.
      

      Analysis

      This identical failure appears on three separate stable release branches (10.11, 11.4, 11.8), all funneled through the single builder amd64-msan-clang-22, so it looks like a builder/environment-level issue (MSAN build config, port allocation, or a shared .cnf/include regression specific to that builder) rather than a per-branch code regression. No occurrences on any other builder in this window.
