A DESCRIPTION OF THE PROBLEM :
Segmentation fault occur on condition that a little swap area. This test program is 100000 threads make and start. I hope that segmentation fault don't occur.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.condition that a little swap area

2.run test program
 >java ThreadTest

3.Segmentation fault occur

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected:
 >java ThreadTest
 >Make Thread Start
 >Make Thread End
 >
 or
OutOfMemoryError
(I hope don't occur Segmentation fault)

Actual Results:

Alexey Gibadullin, ###@###.###

I have developed a testcase for the testbase_nsk based on
ThreadTest class. The test will be shipped with 16 release
of testbase_nsk; and the test name will be:

    nsk/regression/b4654928
    
The location of the testbase:

    /net/sqesvr.sfbay/export/vsn/VM/testbase/testbase_nsk
    
I could reproduce the crash against Hopper-b15 on Linux Rad Hat 7.2

$ uname -a
Linux java9 2.4.9-31smp #1 SMP Tue Feb 26 06:55:00 EST 2002 i686 unknown

The failure is intermittent (about 1/40) and I observed the crash with
-Xcomp option against Server VM only.

I used a small sh-script to wait for the crash:

-----------------------------------------------------------------
while [ true ];
do
    ../jdk1.4.1-b15/linux-i586/bin/java -server -Xcomp ThreadTest
done
-----------------------------------------------------------------

and the output was:

Make Thread Start
Make Thread End
Make Thread Start
Make Thread End
Make Thread Start

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x4002FBA0

NOTE: We are unable to locate the function name symbol for the error
      just occurred. Please refer to release documentation for possible
      reason and solutions.
