First lines from m000 trace after the header:

the last few entries are:

jolz: Compiled code for oracle/aurora/zephyr/backend/LiveLIRTemps$EnsureLoserLiveRangeIterator.apply; uses a CPU feature which is not available
jolz: Compiled code for oracle/aurora/zephyr/backend/LiveLIRTemps$GenBitSetIterator.apply; uses a CPU feature which is not available

This eventually leads to ORA-07445: [joe_run_vm()+15316] [SIGSEGV] [ADDR:0x24000] [PC:0x33FAB74] [Address not mapped to object] []

What is causing the "CPU feature which is not available" messages to be reported?


Thank for any assistance.
