Hi , I was trying to test algorithms with huge int arrays when i started getting segfaults..here is a simple program which emulates this behaviour... Each time i run this program , it segfaults , This might be very naive ..but can anyone help me with what I am missing here ? static const int N=10000000; int main() { int c, i[N]; for (c=0;c<N ; c++ ) i[c]=c; } Thanks Digz
