lib/libc/gen setproctitle.c
Log:
When recording the original arguments, stop short if we encounter
a NULL argument. Some programs change the contents of the argv
array, typically to remove some special arguments. They shorten
argv by storing a NULL where an argument pointer used to be. Such
programs core dumped if they called setproctitle(), because it
would try to apply strlen() to a NULL pointer.
