After running coverity tool I discovered following memory leaks.
1) in gcc/opts.c: memory never freed allocated by 'new_option' pointer.
2) in gcc/df-core.c: Memory never freed allocated by 'postorder' pointer.
3) in tree-data-ref.c: memory never freed allocated by dist_v and init_v
pointers.
I'll submit the patches to fix these leaks.
