           Summary: valgrinding the JVM fails with a sanity check assertion
           Product: valgrind
           Version: 2.3 CVS
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: jseward acm org
        ReportedBy: thh cyberscience com


Running the JVM under valgrind fails with a sanity check assertion. The command
used was:

  valgrind --tool=memcheck --trace-children=yes /usr/java/jdk1.5.0/bin/java

the output produced is:
