arm-elf-ld generate arm interworking stub at bad address ?

[Sylvere TEISSIER]

Hi,
when I link mixed thumb and arm code with interworking, the linker
insert a .stub section at the beginning of the memory. 

But, like expressed in my linker script present bellow, I want my
exceptions vectors assembled with ".section .startup" at the origin of
the memory.

Why ld doesn't place this stub at other place ? 
Is there something wrong with my linker script ? Or is it a bug ?

I have this problem with both binutils-2.18.50 and binutils-2.19.50

bellow:the linker script and map output

. = ALIGN(4);
_bss_end = . ;
