Description Karel Zak 2010-11-08 09:13:54 UTC 
+++ This bug was initially created as a clone of Bug #613716 +++

Description of problem:
/usr/bin/column throws a segfault when run with '-t' and '-s%c' (where %c is any character AFAICT) with that character passed in on standard input.

How reproducible:
echo % | column -t -s%

  
Actual results:
Program terminated with signal 11, Segmentation fault.
#0  __wcslen (s=0x0) at wcslen.c:30
30        while (s[len] != L'\0')
(gdb) bt
#0  __wcslen (s=0x0) at wcslen.c:30
#1  0x00000039ad46476e in fputws (str=0x0, fp=0x39ad751780) at iofputws.c:37
#2  0x000000000040181c in maketbl (argc=<value optimized out>, argv=<value optimized out>) at column.c:274
#3  main (argc=<value optimized out>, argv=<value optimized out>) at column.c:140


Expected results:
Blank


Additional info:
This is the same problem as the one util-linux-ng experiences in bug #579955, but I am filing this again since el5 has a different packge name.  I suspect that it also occurs in el6, given that F12 and F13 have the problem.
