    Description

      Has originally been spotted with:

      vmTestbase/vm/mlvm/meth/stress/compiler/deoptimize/Test.java

      Seems like it's not the only one:

      vmTestbase/vm/mlvm/meth/stress/compiler/sequences/Test.java

      Has been seen only in macosx-aarch64 so far. I tried linux, macosx with x64 and aarch64, in both release and debug configurations, only macosx-aarch64 showed the problem (approx. one out of 10 runs). The memory pool in question is 'Non-segmented code cache' (the test was started with '-XX:ReservedCodeCacheSize=100m -XX:+CreateCoredumpOnCrash -XX:TieredStopAtLevel=2').

      The stacktrace:
