NEWHPROF: Occasional SEGV at VM_DEATH on Linux due to slower child threads

    Details

    • Subcomponent:
    • Resolved In Build:
      b54
    • CPU:
      generic
    • OS:
      generic

      Description

      The thread end callbacks can be slower, much slower on smaller Linux machines,
      and raw monitor actions may still take place after VM_DEATH, and even after
      Agent_OnUnload(). Some raw monitor functions need to be aware of when the
      JVMTI environment is gone, or the raw monitor is NULL, and do nothing.
