Linker scripts always produce a misaligned stack pointer

All of the ST tools seem to generate a misaligned stack pointer.

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/14269.html

States a multiple of 8 bytes. yet it's always:

<mem base> + <mem size> -1

this seems to be from the early days of 8bit, but even then it was wrong as a push is

SP--;

*SP = <reg>;

and pop

<reg> = *SP;

SP++;

So why is it misaligned?
