Ok, I fixed the crashes by adding -mlong-calls to the example.c compile command line and by fixing an error in my code (duh, uncomment the exit call after the error reporting "not enough memory" else the code will go on and crash...I should have thought of that waay earlier)

Other than that the code still won't allocate the memory.

I am so amazed at the quick response time. Thank you.

#include <limits.h>
#include <float.h>
#include <math.h>
#include <setjmp.h>
#include <ctype.h>
#include <string.h>
#include <errno.h>
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
etc.

I'm guessing that is newlib. I never included <os.h> in any file in the code.

"insert a message": how? why? Like a debug message?

I used nspire-gcc and do not think I added the -mlong-calls to the command line (I ran the command a while ago and can't revive my history listing...)
As for modifications, I changed DEFAULT_N_TOKENS to 100 instead of whatever it was (in am.h), and I think whatever I needed to do to get rid of errors. And I changed example.c to fit the nspireio2's functions. (I'm using example.c for my testing purposes. Also I'm using the library and linking it to example.o.)

I'm going to re-compile everything now so I can get more precise information for you. Should I add the -mlong-calls to the command line? Should I not use nspire-gcc?
