-
-If the assignment of stop overflows due to idx and count being
-larger than SIZE_T_MAX in sum, out of boundary access could happen.
-
-It takes invalid usage of this function for this to happen, but
-I decided to add this check so array_list_del_idx is as safe against
-bad usage as the other arraylist functions.

-Subject: [PATCH] Fix integer overflows.
-
-The data structures linkhash and printbuf are limited to 2 GB in size
-due to a signed integer being used to track their current size.
-
-If too much data is added, then size variable can overflow, which is
-an undefined behaviour in C programming language.
-
-Assuming that a signed int overflow just leads to a negative value,
-like it happens on many sytems (Linux i686/amd64 with gcc), then
-printbuf is vulnerable to an out of boundary write on 64 bit systems.
