/* ---------- "rn 4.3 patch #36" ---------- */
System: rn version 4.3
Patch #: 36
Priority: depends
Subject: Rn can dump core on 16 bit machines
From: mn-at1!alan (Alan Klietz)
Description:
Rn dumps core on 16 bit machines when adding a new
newsgroup to the .newsrc file.
Repeat by:
Create a new newsgroup and then run rn.
It will dump core.
Fix:
The birthof() procedure fails to coerce the null pointer
to the time() system call to (long *). This results in
a 16 bit quantity being pushed on the stack which is
derefernced by the time() system call as a 32 bit quantity.
This results in a segment violation.
The fix is to use a properly coerced pointer.
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.
If patch indicates that patchlevel is the wrong version, you may need
to apply one or more previous patches, or the patch may already
have been applied. See the patchlevel file to find out what has or
has not been applied. In any event, don't continue with the patch.
[Note, I cannot test this patch because rn is being rewritten--law]
If you are missing previous patches they can be obtained from me:

If you send a mail message of the following form it will greatly speed
processing:
Subject: Command
@SH mailpatch PATH rn 4.3 LIST
where PATH is a return path FROM ME TO YOU in bang notation, and LIST
is a list of one or more patches you need, separated by spaces, commas
and/or hyphens.
