I'm having some trouble declaring a multi-dimensional array of doubles in Cocoa using 10.1.5.

double d[10][10]; works fine, however larger sizes cause a crash.

For instance, double d[256][256]; will compile but result in EXC_BAD_ACCESS.

Is there another step I need to take when allocating memory for these arrays?

Try using Objective-C++:

double *d[][] = new double[256][256];

Just a thought.


I've always had problems with multidimensional arrays (C, C++, etc...). I tend to use single dimensional arrays and create a wrapper class to create the illusion of multiple dimensions. I have a matrix class, for example. The implementation is a single dimensional array, but you use it the same as any 2d matrix.
