>Confidential: no
>Severity: non-critical

>Release: FreeBSD 2.2.2-RELEASE i386
>Environment:
FreeBSD-2.2.2 with tcsh under X
>Description:
fmt experiences Bus error when one tries to format
a text that starts with ^M (CR) (e.g. from an MSDOS
system) or another non-printable character.
This bug was already handled and removed for FreeBSD 2.2-BETA_A
under `bin/2968'.
>How-To-Repeat:
In the simplest case:
1:05 ghost: /home/re 0% printf '\r'>fmttest
1:05 ghost: /home/re 0% fmt fmttest
Bus error (core dumped)
>Fix:
Gareth McCaughan (gjm11@dpmms.cam.ac.uk) supplied the following
patch for 2.2-BETA_A, which also works for 2.2.2:
*** fmt.c.orig Mon Sep 22 23:28:42 1997
--- fmt.c Mon Sep 22 23:25:01 1997

#define CHUNKSIZE 1024
! static int lbufsize = 0, cbufsize = CHUNKSIZE;
!
! canonb = malloc(CHUNKSIZE);

! abort();
