Should I free memory before exit?

Question

Should I free all my mallocated memory when I am exiting program in the due of error?

something = (char**) malloc (x * sizeof(char*));
for (i = 0; i < x;          


        

Answer 1

I had completely opposite scenario: segfaulting destructors of static objects from third-party library. Just because of explicitly freeing memory pools before exit. I believe, it is better to be reasonable and to concentrate on program structure.
