hi, André
For your trouble with "print" function, as Michiel say you shouldn't use
this fonction (printf in libc)
It doesn't support 20 bit addressing, because it use function pointer !
==> int vuprintf(int (*func)(int), const char *fmt0, va_list ap)
It'll crash even if it's located into the lower memory space.
The compiler process function pointer with only 16 bits, and then it
make "calla" with 20 bit addressing !
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
Try another printf function your test ! for example this one =>

Look at this previous post, you can find some tips :

It's possible to use all memory MCU space !
I use MSP430X compiler for MSP430F5418 for my project since a few
months, and it's about 64K, and grow up day by day ...
I put all my datas and my functions called by pointers below 64K!, and I
use specific function call describe on the post !
My compiler option is : OPT_CPU = -mdata-64k
