Description of problem: The following code snippet: import java.lang.Character; public class test { public static void main(String[] args) { boolean b = Character.isLetterOrDigit(-1); System.out.println("b is " + b); } } causes a NullPointerException when run on x86_64 with libgcj-4.1.2-8 The same test case works fine on i686. This problem was initially reported against eclipse-cdt when editing a configuration file.

I checked in a fix for this to GCC svn. I'm not clear on when it will be possible to merge it into an FC build. It is r124370.
