I: [PATCH] realloc-related memory leaks fixes

["Dmitry V. Levin" <ldv at alt-linux dot org>]

Greetings!

I've reviewed current glibc code for common realloc usage errors.
Following problems have been found:

- 10 files contains classic memory leaks (patch attached);
- __argz_add_sep() contains possible memory leak; its semantics differs
  from other argz functions (patch attached);
- resolv/res_hconf.c seems to have memory leak (possible fix also
  attached);
- misc/err.c:convert_and_print() and misc/error.c:error_tail() functions
  contain ugly code filled with memory leaks; it have to be rewritten if
  ever used.
- nis/* also contains classic memory leaks to be fixed.
- io/fts.c contains memory leaks; I'd suggest to update code from BSD; for
  example, OpenBSD have these bugs fixed.


Regards,
	Dmitry

UNIX is user friendly. It's just very selective about who its friends are.
