The problem is reproducible with b31. vtest failed intermittenly with b31 with
-server -Xcomp flags. Not sure if the failure in b31 is still the same as
bug 4937752.
core file is under /bt/VolanoTestrun.151.-server on machine bigapp-880-1.red.iplanet.com ( contact me for root passwd )

It's easier to reproduce the bug using CMS GC.
