See From 0507dfad5f060161f01840067e1bb1615257b636 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= Date: Mon, 8 Jun 2015 17:27:56 +0200 Subject: [PATCH] Do not rely on PATH_MAX when reading a symlink target. * src/util.c (move_file, copy_file): Use 'fromst->st_size + 1' and 'tost->st_size + 1' for the allocation, and 'fromst->st_size' and 'tost->st_size' instead of PATH_MAX.
