Requesting fix of SIGSEGV issue



      On embedded device SIGSEGV with the backtrace like the following occurs frequently.

         pc lib addr location
      3 0x45c5f344 libjvm.so 1b0344 <CounterDecay::do_method(Method*)>+0x14

      5 0x45c5d0d0 libjvm.so 1ae0d0 <NonTieredCompPolicy::do_safepoint_work()>+0xc0
      6 0x45fee4d8 libjvm.so 53f4d8 <SafepointSynchronize::do_cleanup_tasks()>+0x8c
      7 0x45feed04 libjvm.so 53fd04 <SafepointSynchronize::begin()>+0x6bc
      8 0x460f2370 libjvm.so 643370 <VMThread::loop()>+0x4ec
      9 0x460f251c libjvm.so 64351c <VMThread::run()>+0x78
      10 0x45f870fc libjvm.so 4d80fc <java_start(Thread*)>+0x168

      This issue seems to occur regardless of CPU because the same SIGSEGV has
      occurred several times on simulators of nearly identical configuration other
      than CPU, and the following backtrace has appeared.

      This simulators CPU is Intel using binary built from the 8u161 source code.

      From investigation, a related bug report was found.
      This bug seems to be occurring in the Intel 64-bit environment, but there is considerable similarity in the above backtraces.
