      Name: dkC59003 Date: 12/09/99



      HotSpot 1.3fcs-Q crashes while executing nsk/coverage/runtime/runtime010 test
      if -Xrunhprof:cpu=samples option is used.
      In debug mode, assertion failure occurs: "scopeDesc must exist".
      Classic passes the test as well as 2.0rc1-I.

      Log and test source follow:
