The request is to use a higher alignment than necessary when allocating large
arrays which might result in better performance. I've proposed patches for
malloc to automatically overalign large allocations.
Note small allocations could use alloca rather than malloc even without
-fstack-arrays - this would give Fortran code built with -O2/-O3 a big boost
and avoid the issues caused by -fstack-arrays.
