 Hello,
 
 I can verify that on 3.2, 3.3 branch and mainline (20030510) on  
 i686-linux, the same error occurs:
 EnclosingCall.java: In class `EnclosingCall$Inner':
 EnclosingCall.java: In constructor `(EnclosingCall)':
 EnclosingCall.java:12: error: Can't reference `this' before the  
 superclass constructor has been called.
         this(foo());
              ^
 1 error

Another test case distilled from classpath's TreeMap.

GCJ reports: EnclosingCall.java:12: Can't reference `this' before the superclass constructor has been called.

... but we don't need to access this to call foo() - only this$0.
>How-To-Repeat:
public class EnclosingCall
{
  int foo()
  {
    return 5;
  }
  
  class Inner
  {
    Inner()
    {
      this(foo()); 
    }
    
    Inner (int i)
    {
    }
  }
}
