Hi Joachim,
If you are declaring the array on the stack, you've probably exhausted your stack. The work around is to get/release the storage of your array using C++) new and delete, C) malloc and free. Since you have a two-dimensional array, you'll have to account for that yourself, via allocarray[a * 100 + b] access.
If you are declaring the array in the .bss or .data section, you've probably exhausted available memory (including virtual memory), or have exceeded the limits of the architecture. The work around is to store the array in a file, and access it through either a smaller chunk of the array -- which you "swap" in and out through your array window (slow) or which you manipulate pretty much directly (slower, but easier to implement).
HTH, --Eljay
