MS COFF output BUG?

i`m using fasm to make some object file, later linked with LINK.EXE from masm32 package. what`s the point? something is going wrong, when i`m trying to define more than 9 DATA sections. with 9 sections, after linking, RAW data in EXE output`s section is zeroed, as i want, but if i have 10, and more, sections, there are pieces of sections headers (!)..

linking this example will say more than thousand words:

Code:

format MS COFF
extrn "__imp__MessageBoxA@16" as MessageBox:dword
public _demo

section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50
section ".bss" data readable writeable
        rd 4*50

section ".text" code readable executable

 _demo:
        push    0
        push    _caption
        push    _message
        push    0
        call    [MessageBox]
        ret

section ".data" data readable writeable

 _caption db "Win32 assembly",0
 _message db "Coffee time!",0

parameters:
link.exe /subsystem:windows /entry:demo main.obj d3d9.lib gdi32.lib kernel32.lib user32.lib

is it FASM bug?
i don`t think, that linker does mistake, because the same thing is happening with other linker (packer) - crinkler.
or am i stupid and not reading faq? :)
