Subject: libc6-dev: regexp.h compares to 'n' rather than '\n'

Date: 16 Dec 1998 14:08:45 +0200

Package: libc6-dev
Version: 2.0.7u-5
Severity: wishlist

Line 134 of /usr/include/regexp.h:
      if (__ch == '\0' || __ch == 'n')

This is just a guess, as I've never used this code, but shouldn't this
compare __ch to '\n' rather than 'n'?  The comment on lines 93-98 says:

/* Get and compile the user supplied pattern up to end of line or
   string or until EOF is seen, whatever happens first.  The result is
   placed in the buffer starting at EXPBUG and delimited by ENDBUF.

   This function cannot be defined in the libc itself since it depends
   on the macros.  */

There's a bug in the comment as well: the real parameter is expbuf,
not expbug.

I set the severity to wishlist because I'm not sure of these being
bugs and programs shouldn't use this header anyway.

Hi,

this has been fixed in between:

asterix:~$ grep -n EXPBUG /usr/include/regexp.h
asterix:~$ grep -n "__ch ==" /usr/include/regexp.h
136:      if (__ch == '\0' || __ch == '\n')
asterix:~$
