You don't provide all the necessary details for anyone to be sure, but
this very strongly feels like you're blowing the stack.  Don't make
large variables like this automatic (i.e. local to some function).
The usual recommended solution is to use the heap instead of the
stack, i.e. use 'new' or malloc(), depending on what language you're
working in, or make such variables static.
