Java HotSpot Client VM build 1.3-P in compiled mode (-Xcomp option) crashes without
notification while running test vm/instr/astore_w/astore_w004/astore_w00401
from jck1.3 i.e. at invocation of method with large number of locals.
 
This is observed on winNT.

To reproduce the bug run do.bat (source text bellow)

Test passed on the classic VM and on HotSpot Client VM in mixed mode (witout options)
and in interpreted mode (-Xint)

Test was improved (The catching of StackOverflowError and OutOfMemoryError
was addeed in the test. See bug #4280626).

Running under winNT the do.bat outputs:

>do.bat
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-P)
