Do you mean compiling the compiler? If so than for real tests you SHOULD 
NOT compile the compiler by hand, but only through "make cycle" in the 
compiler directory or "make all" in the top level directory. This will 
ensure that the compiler is compiled correctly.

And yes, I know the problem with -B and it's likely related to unit 
loading. This normally happens only in more complex projects like the 
compiler. Though I've just managed yesterday to create a smaller example 
(by accident) that also chrashes. Maybe I'll find the problem and can 
fix it once and for all :)
