Compiler crash with an NPE with code using @Trait with an init block

[GoogleCodeExporter]

The compiler crashes with an unhandled NPE in compiling the following piece of 
code
-----------------------------------------------------
@Trait class T {
    {println a}
    Integer a = 1
}

class C implements T {
    Integer getA(){
        2
    }
}
-----------------------------------------------------

A smaller snippet also makes the compiler crash with NPE but at a different 
place (going by the stacktrace)

-------------------------------
@Trait class T {
    {println 1}
}
-------------------------------

I think instance initializers don't make sense for traits either, it's in line 
with no constructors for traits.

I agree. 

They are the same thing and if g++ decides not to support instance constructors 
in trait classes, then the fix should ensure that both (constructor and 
instance init blocks) are rejected by g++.
