Hi Stanley,

In working with the EB40 (not eCos) I have found a strange condition where 
symbols imported from the linker script sometimes don't get the right 
address. I haven't been able to isolate this problem yet, nor have I tested 
with a newer snapshot of binutils (currently working with 2.10).

(well, to be accurate: in any linker script I've handwritten, the function 
hasn't worked right. Only with other peoples' code does it seem to work 
correctly, and I haven't been able to work out the difference yet).

Anyway, I think it likely you're getting a similar problem. The symbol 
marking end of BSS is getting the same address as the start of BSS, which 
is exactly the problem I have in my handwritten linker scripts.

them accordingly."
