From f3f1b8bb63a574853e2fbcafe47b121da972ca23 Mon Sep 17 00:00:00 2001 From: Marcus Meissner Date: Mon, 1 Sep 2008 10:27:25 +0200 Subject: attribute alloc_size for newer gccs. This patch marks up the allocator functions with the GCC 4.3 (and later) attribute alloc_size. This will pass the size of allocations of known size (at compile time) to the overflow checking memcpy/strcpy and related functions.
