This bug is still reproduced under JDK1.2fcs-C and causes core
on x86 solaris and crash on NT:
"The exception unknown software exception (0x00000fd) occurred in the
application at location 0x503066f7
Click OK to terminate the application."
The difference between sparc 1.2fcs-C and 1.2beta4 is that it reports
stack overflow in 37 minutes instead of 4 hours.

======================================================================


Name: laC46010 Date: 07/20/98



VM (1.2beta4, x86,win32) core dumps while trying to create object with
780 deep inheritance tree. It happens only with jit enabled on win32 and
x86 platforms. With jit disabled on those platforms VM produces
long (332Kb) StackOverflowError exception trace.
  On solaris platform (Ultra-1) it produce short StackOverflowError
exception message after 4 hours of work (!).
  Note that version 1.0.2 and 1.1.x work well and execute it
very fast while creating object with more then 2000 deep
inheritance tree.

An example and VM diagnostics follow:
-------------------------------------------------------
import java.io.PrintStream;

public class test {

    public static void main(String args[]) {
        System.exit(run(args, System.out) + 95/*STATUS_TEMP*/);
    }
 
    public static int run(String args[],PrintStream out) {
       Object o = new cl779();
       return 0;/*STATUS_PASSED*/
    }
}
