        Description

        The attached test program causes the VM to abort with a SEGV around 30%
        of the time on Intel systems with the -client option.

        The source fine must be compiled with the "-source 1.5" option. It requires
        a J2SE build with the JSR-166 library changes which can be found under:

          /home/mb29450/ws/jsr166/build/solaris-i586 (solaris-x86)
          /net/polgar/u/martin/src/jsr166/images (other systems)

        The failure usually occurs in java.util.concurrent.ConcurrentHashMap$Segment.get(), but I don't see anything
        obviously wrong with the generated code for this method. It may just be
        using a value that was corrupted someplace else.
