That's definitely a OS problem - in other OSes IDL 32 can
allocate a 500 cubed dblarr without problems. The rule is:
on IDL 32 bit the maximum size of an array is about 2^31
bytes (2GB). The max number of elements is about 2^31/S,
where S is the size of one elements in byte (2 for INT, 4 for
FLOAT etc.).
