Hrm, what I'm getting isn't very helpful:

I've done a bit of printf-style debugging, and I think an exception is
getting thrown in a class member initializer -- like this

    public class foo {
      Bar bar = new Bar();
      foo() { .... }
    }

Where Bar's constructor is throwing an exception.

Normal JVMs throw the exception out of the "new foo()" call -- but it
seems that GCJ doesn't work this way. Is that the case?
