Ignore the testcase in #9. Got a good version which always works in terms of producing a mysqld crash. Uploading below. The GLIBC is not produced, but perhaps once in a while it could be (reduction was done on the GLIBC crash occurring, not mysqld crashing). It is highly sporadic, though regularly seen during overall QA trials. Then again; there are different GLIBC crashes. It is unclear if they are all related to the ON/OFF of scalability_metrics_control.
