[4.3bsd] DESCRIPTION: If msgs finds an out of bounds .msgsrc it warns the user and truncates it in preparation to reset it to a more sane value. Unfortunately, it calls ftruncate() on a file (.msgsrc) it just fclose'd. REPEAT-BY: Set your .msgsrc to some ridiculously high value, run msgs, get warning message, quit. Look at .msgsrc file, it will have two lines in it rather than one. FIX: Change (the only) ftruncate(fileno(msgsrc),0); to truncate(fname,0); (the code then goes on to re-open the file shortly thereafter so it can update it.) -Barry Shein, Boston University
