Elena,

I implemented your suggestion, but I stumbled accross another problem
that puzzled me.

the program that I provided as an example to reproduce the problem
does in fact contain some symbols located in the .bss section ('end' for
instance), but gdb could had not located it. I verified this by using nm:

List of symbols in the .bss section:
<<
% nm -B mach | grep ' B '
0x00000140000160 B .bss
0x00000140000160 B _ebss
0x00000140000160 B _end
0x00000140000160 B end
>>

List of symbols in the .sbss section:
<<
% nm -B mach | grep ' S '
0x00000140000140 S .sbss
0x00000140000140 S __Argc
0x00000140000158 S __Argv
0x00000140000150 S _auxv
0x00000140000140 S _fbss
0x00000140000148 S _ldr_present
>>

Unfortunately, I don't have enough time to persue this right now. In
think my changes improve a bit the current situation, but do not fix all
problems, so I'm not sure they should be submitted yet.

I'll look into why gdb can not find this .bss section when I have more time
available.
