I also get the exact same behaviour using...

gcc -v 
Reading specs from /usr/share/gcc-4.0b/lib/gcc/i686-pc-linux-gnu/4.0.0/specs
Configured with: ../gcc/configure --prefix=/usr/share/gcc-4.0b --enable-java-awt=gtk
Thread model: posix
gcc version 4.0.0 20041217 (experimental)

Trying to compile this code...

public class testish {
    public static void main (String args[]){
	Number pang = null;
	double pong = pang.doubleValue();
	if (pong != null){
	    System.out.println("well...");
	}
    }
}

/usr/share/gcc-4.0b/bin/gcj -C testish.java
testish.java: In class 'testish':
testish.java: In method 'testish.main(java.lang.String[])':
testish.java:5: internal compiler error: in generate_bytecode_conditional, at
java/jcf-write.c:1271


I guess this should compile, as not testing for the null causes a run time null
pointer exception (as shown in comment #2)
