HotSpot 2.0-rc2A (win32) crashes while trying to execute the JCK-stress test
jck12a003: when executed in -Xcomp mode under WinNT 4.0, java_g.exe terminates
with the following diagnostics:
    #
    # HotSpot Virtual Machine Error, assertion failure
    #
    # assert(test != 0, "Unexpected object header as 0!")
    #
    # Error ID: C:\hotspot2\src\share\vm\runtime\synchronizer.cpp, 176
    #
    # Problematic Thread: prio=5 tid=0xf927eb8 nid=0x12b runnable
    #

This crash looks like a regression of the bug #4287571

Note also, that java.exe intermittently terminates with the following
diagnostics (while trying to execute jck12a003):
    #
    # HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION
    #
    # Error ID: 4F533F57494E13120E43505002D9
    #
    # Problematic Thread: prio=5 tid=0x2f590940 nid=0x328 runnable
    #
(ErrorID == "os_win32.cpp, 729")

This kind of crash looks the same as the HS crash described by #4308797
