Maximun array size in g++.

[Pe?a Arellano Fabi?n Erasmo]

        Hi,

        For a program which uses the fast Fourier transform to do an
integral, I need to use very large arrays of complex numbers. If the array
size is 2^17 everything works fine, but if the size is 2^18 I get a
segmentation fault error at the line the array is defined. What is the
maximun size an array of complex numbers can be in g++, is there a way to
change such limit?
        Thanks in advance,

        Fabian Pena.
