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. |
