Well, that pic should have enough ram for the array, but:
if the Array is in RAM, the startup code has to initialize it by copying the
values from Flash.
That is usually done by the initialization code in crt0iz.o, which should be
linked automatically.
There are however also other versions of that init code available (crt0i.o,
crt0.o) which skip the variable initialization in order to save code space.
Check your makefiles if you're linking the right one.
