 Sure:
 
 [bryce@reason libjava.lang]$ javac Class_1.java
 [bryce@reason libjava.lang]$ java Class_1 > class1.out.jdk
 [bryce@reason libjava.lang]$ gcj -O2 Class_1.java -o c1 --main=Class_1
 [bryce@reason libjava.lang]$ ./c1 > class1.out.gcj
 [bryce@reason libjava.lang]$ diff -u class1.out.gcj class1.out.jdk
 [bryce@reason libjava.lang]$

 These failures are different from the ones I was seeing before writing the patch. You're failing on some very
 trivial cases like "C.class, D.class" and "J.class, J.class", which seems pretty odd!
 
 I'm using gcc version 2.96 20000607 (experimental), is it possible you have a bad compiler?
