Segmentation fault (core dumped)

Hi Foamers!

When I initialize a 3D array and run it for n=128, it crashes with

Code:

Segmentation fault (core dumped)

The code is part of the solver and does not throw an error during its compilation. But when running on a case, the error pops up. Also for smaller values of n (64,32, 16) it works fine. What could be the problem?

Code:

n= 128;
double array[n+2][n+2][n+2];

Thanks,
Sugajen
