TIOS won't exit() the program if a memory allocation fails (unless TIGCC has
implemented it that way). Instead, you'll get a null pointer or handle returned
from the function, so it's up to you to free all the memory you've allocated. In
most cases you shouldn't have to use malloc() though.
In a related topic, does TIGCC support BSS blocks yet? Can the TIOS support it?
