If your program is executing a declaration it must be an automatic, i.e. on
the stack.  I doubt you have 480K bytes of stack space available!

Putting it on the heap is probably the right thing - assuming you have
enough space in your heap.
If you have (or should have) it could be that your heap has become
corrupted.

The other valid way to store a large object is as a static or global, if
it's something thats needed continuously, or over & over again, in your
application.

This is done in the BSP. Which are you using?  BTW do you really need 120
thousand integers? It does seem a lot.
