Java 2 SDK 1.3.1-b1 Client VM (win) intermittently crashes while
executing the testbase_nsk test:
    nsk/stress/jck12a/jck12a012
which stresses-out hundreds of JCK 1.2a tests by executing them in
concurrent threads.

The crash occurs very rarely (I saw it only after ~10 executions)
and only in -Xcomp mode. Java exits with status code=3, and dies
almost silently; it only displays:
    "abnormal program termination"

After that crash, hotspot.log file appeared in the work directory
which contained the message:
    #
    # HotSpot Virtual Machine Error, unknown exception code
    # Please report this error at
    # http://java.sun.com/cgi-bin/bugreport.cgi
    #
    # unexpected exception occurred
    #
    # Error ID: Z:\hotspot1.3.1\ws\win32\hotspot1.3.1ea\src\os\win32\vm\os_win32.cpp, 837
    #
    # Problematic Thread: prio=5 tid=0xee72b58 nid=0x173 runnable
    #

When I executed "jck12a012" with java_g, it also crashed as
"abnormal program termination", and in addition a debugger's
popup window was displayed with "unexpected exception" message.

The test "jck12a012" is found below the 'src' directory in the
testbase:
    /net/sqesvr/export/vsn/VM/testbase/testbase_nsk

To reproduce this bug, please try the script DOIT.BAT found in
the directory:
    /net/sqesvr/export/vsn/GammaBase/4377159

This failure is also observed for jdk1.4.0beta-b35 (win32)
