      Description

      Test case for MySQL "Bug#59331 filesort with priority queue: handling of out-of-memory" fails in 10.0.

      In fact this bug is fixed in 10.0, but there are two problems causing test case to fail:
      1. Debug point "bounded_queue_init_fail" probe wasn't merged.
      2. "simulate_out_of_memory" probe of my_malloc doesn't report error causing assertion failure.

      Please merge test and fix mentioned above issues.
