Bug Report: sed-4.1.4 misinterprets uClibc's malloc (patch included)
From: Yuri Vasilevski
Subject: Bug Report: sed-4.1.4 misinterprets uClibc's malloc (patch included)

Hi,
Recent versions of sed expect glibc behavior form malloc, i.e.
malloc(0) return live pointer. This is not true for uClibc (and many
other old/classical libc implementations).
So I made and attach a patch to solve this problem. It basically makes
re_node_set_alloc(set,0) behave exactly as re_node_set_init_empty(set).
Yuri.
