> 1. The computer is a 2020 MacBook Air m1 and the operating system is MacOS 12.3. \
> However, I have the same problem on a 2013 Intel MacBook Pro running MacOS 11.6.5. 
> 2. The code is a Fortran code that I compiled using gfortran. The code solves \
> partial differential equations for scientific modeling. 
> 3. The basic problem is that the code has large static arrays so the static storage \
> exceeds 4 GBytes. It seems odd to me that a modern 64bit computer and operating \
> system is limited to 32bit addressing for arrays. 
> 4. I had found the URLs you listed in your email but I didn't find them helpful. \
> That could certainly be because I didn't fully understand them. My limitation. 
> Many thanks for your reply anyway. Much appreciated.
