Subject: getpwent.c: isn't line supposed to be set NULL?
the getpw* functions call getline in a dubious way
for example:
struct passwd *__getpwent_a(FILE *f, struct passwd *pw, char **line,
size_t *size)
[..]
if ((l=getline(line, size, f)) < 0) {
free(*line);
*line = 0;
is called from
struct passwd *fgetpwent(FILE *f)
[..]
static char *line;
return __getpwent_a(f, &pw, &line, &size);
where line is uninitialized.
first thing getdelim (forwarded from getline) does is:
if (!*s) *n=0;
so this looks wrong somewhere.
maybe i'm just missing an =0 in between.
