Follow-up Comment #1, bug #45701 (project avr-libc):
The current startup code allows a custom value for SP init by defining symbol
__stack , for example: -Wl,--defsym,__stack=0x123 or by defining that symbol
in a custom linker description file.
Moreover it is not uncommon to (re)start an application by jumping to 0x0,
e.g. from a bootloader. If the startup code was "optimized" as proposed, that
code will no more work as expected.
