I've adopted the CrashTest into the testbase_vm to fix the RFE:

    5012908 Create stress test for hprof and jvmti from CrashTest

And while checking this test against Tiger-b44, I've observed
a number of failure scenarios:

(1) VM crash, core file:

    ## Problematic frame:
    ## C [libhprof.so+0x11080]

    System:
        solaris-sparc (Sun E250, Dual CPU, RAM 1024Mb, Solaris 9):
    
    Command line:
        java -Xrunhprof:cpu=samples CrashTest 3000

(2) VM crash, though no core file:

    # Internal Error (53484152454432554E54494D450E43505001A1), pid=3771,
tid=1548217792

    System:
        linux-i586 (Pentium-III, Dual CPU, RAM 512Mb, RedHat 9.0):

    Command line:
        java -Xrunhprof:cpu=samples CrashTest 3000

(3) VM crash, though no core file:

    HPROF ERROR: Cannot exit with raw monitor (JVMTI Error ?(116))
[../../../src/share/tools/newhprof/hprof_util.c:297]

    Systems:
        solaris-sparc (Sun E250, Dual CPU, RAM 1024Mb, Solaris 9):
        linux-i586 (Pentium-III, Dual CPU, RAM 512Mb, RedHat 9.0):

    Command line:
        java -Xrunhprof:cpu=samples CrashTest 3000

(4) Error message, but no VM crash:

    HPROF ERROR: MonitorWaitedEvent missing MonitorWaitEvent?
[../../../src/share/tools/newhprof/hprof_monitor.c:424]

    Systems:
        solaris-i586 (Pentium-III, 1xCPU, RAM 512Mb, Solaris 8)
        linux-i586 (Pentium-III, 2xCPU, RAM 512Mb, RedHat 9.0)
        windows-i586 (Pentium-III, 2xCPU, RAM 512Mb, Windows 2000)

    Command line:
        java -Xrunhprof:monitor=y CrashTest 300

(5) Error message, VM abort:

    HPROF ERROR: Unable to get necessary JVMTI capabilities.
[../../../src/share/tools/newhprof/hprof_util.c:1145]

    System:
        windows-i586 (Pentium-II, 1xCPU, RAM 384Mb, Windows 98SE)

    Command lines:
        java -Xrunhprof:cpu=samples CrashTest 300
        java -Xrunhprof:cpu=times CrashTest 300
        java -Xrunhprof:cpu=old CrashTest 300
        java -Xrunhprof:monitor=y CrashTest 300

    Caution:
        This kind of failure looks Win98-specific;
        I cannot reproduce it for Windows 2000.

(6) Error message, VM abort:

    HPROF ERROR: can't create temp heap file: \s3vvc373.
[../../../src/share/tools/newhprof/hprof_init.c:696]

    System:
        windows-i586 (Pentium-III, 2xCPU, RAM 512Mb, Windows 2000)
        windows-i586 (Pentium-II , 1xCPU, RAM 384Mb, Windows 98SE)

    Command line:
        java -Xrunhprof CrashTest 300

(7) VM hang-up:

    System:
        linux-i586 (Pentium-III, 2xCPU, RAM 512Mb, RedHat 9.0)

    Command line:
        java -Xrunhprof:cpu=samples 3000

All these failures are intermittent.

These failure affect the following tests:

    nsk/hprof/regression/CrashTest/ct01t
    nsk/hprof/regression/CrashTest/ct05s
    nsk/hprof/regression/CrashTest/ct05t

I'm displaying the test names here to put them
into the vm.knownbugs list of known failures.

A new though similar crash is observed against Tiger-b46:
    
    $ java -server -Xcomp -Xrunhprof:cpu=old CrashTest 3000
    Launching: 3000 Worker threads

This crash is observed against Solaris/x86; the affected
test is:
