Rn bug patch #12 (REPOSTED)

[Jonathan Biggar]

System: rn version 4.1
Bug #: 12
Priority: MEDIUM
Subject: missing free() on pdp11's
Index: head.c
Prereq: 4.1
From: pur-ee!Physics:crl  (Charles LaBrec)

Description:
	On a machine without CACHESUBJ defined, too much subject searching
	and listing can run rn out of memory.  In head.c, in fetchsubj(),
	without CACHESUBJ, if copy is false, then after the call to
	safecpy(), you must do a free(s), or you lose mem.

Fix:	From rn, say "| patch -d DIR", where DIR is your rn source directory.
	Outside of rn, say "cd DIR; patch <thisarticle".  If you don't have
	the patch program, apply the following by hand, or get patch.
