However, and that is my question/suggestion: Why not use Calloc+Free instead of R_alloc in vmmin (and maybe in other places)? I made the changes in 'optim.c' in the functions 'vmmin' and 'Lmatrix'. Then I rebuilt and reinstalled R-2.0.1. The result was great! My function ran very fast and without any memory problems.
So why not? Or will this change create other problems?
Memory will leak permanently if the functions are interrupted or an error occurs. This may be less serious now than it was in the past, since R can be interrupted in fewer places.
