ld overwriting output sections???

[Jakub Jermar]

Hello binutils people,

my team discovered a strange problem with the linker script which I attach to 
this email.
Depending on the presence of the line containing:

LONG(0xdeadbeaf);

the kernel image is linked together correctly (line is present) or the .mapped section overwrites 
the .unmapped section (line is not present).

We use binutils 2.16 cross compiled for IA-32.

Is there anything wrong with our linking process or is it a bug in ld?

Please, Cc: me as I don't read this mailing list.

Thanks for your help,
Jakub
