Actually the second of the two CALLAs will directly cause a crash if
Address_storage points to something in lower 64k.
CALLA with a register that has been loaded 16bit will extend the upper 4
address bits with 0.
The first instruction, however, will try to load 32bit from Address_storage,
which of course will mos tlikely return something wrong.

The generated assembly instructions look like :
Address_storage:
.word _Function_Address_Only_16_bit_are_stored_
calla Address_storage ; cause a cash
mov #Address_storage, R15
calla @R15 ; cause a crash
