[Bug binutils/9749] New: The section is put not in order

[uzytkownik2 at gmail dot com]

I'm not quite sure if it is a bug or feature request (at least on mailong list
it was pointed out as bug). I try to produce an ELF in multiboot format -
therefore the setup section have to be within 0x2000.

If I add big data to .bss section I recive such layouts:
Gold:
There are 8 section headers, starting at offset 0x8108:
