I am sure it isn't a limit on array index values.  How is the array
allocated?  Global, static, local or malloc?

I would guess it is local and that you are seeing a stack problem.
Possibly your program is built with too small a stack limit to
handle the nearly quarter-meg array.

I have seen some things that seem to indicate there may be a limit
on the increment by which the stack can grow, even when it doesn't
overflow its full limit.  (Does anyone more knowledgable want to
comment on that one?)  A quarter Mb is an unusually large
increment to grow a stack.
