This is full trace for coff_XXX_reloc() 


		ldwrite ();
		bfd_final_link()
		default_indirect_link_order()
		bfd_get_relocated_section_contents ()
		bfd_perform_relocation ()
		coff_XXX_reloc ()

/****************************/
For the code below

	_y:
        .short  _x+0
        .short _xx+0
        .short _xxx+0
        .global _z
        .align  1
	_z:
        .short  1
        .comm _xxx, 4
        .comm _xx,5
        .comm _x,6
	


For the background of the problem

Ian:

It's hard to say without more information.  What is the backtrace when
coff_XXX_reloc() is called?  There are several possible paths to that
point, and I'm not sure which you are using.

Thanks, but I need more.  Can you provide the full backtrace?

I don't think that indicates a problem.  You can't predict the order
of common variables.
