Details:
This is http://bugs.debian.org/438689 submitted by Reuben Thomas.
This causes a segfault:
env -u PATH find /tmp -exedir /bin/echo \;
The bug applies to both 4.2.x and 4.3.x and is caused by this code in
parser.c:
-----------------------
static void
check_path_safety(const char *action, char **argv)
{
const char *path = getenv("PATH");
char *s;
(void)argv;
s = next_element(path, 1);
-----------------------
Invoking next_element with NULL is only supposed to happen if it has been
called before with non-NULL argument to initialize path.
