Stepping into java.lang.String.<init> during the call of a
constructor with a String literal argument causes an invalid memory
reference in java_g.exe.

Sample Program:

public class BugDemo {
     public static void main(String argv[]) {
        String foo = new String("foo");
    }
}

To illustrate this, enter the following commands in jdb:


load BugDemo
stop in BugDemo.main
run BugDemo
step
next



After the step, jdb indicates that the program is stopped in
java.lang.String.<init>, presumably to construct the String
corresponding to the literal "foo". If at this point, one enters a
next command, an invalid memory reference occurs in java_g.exe.
