Bug: strip_crlf function has no protection against NULL strings
Discovered in: AFKMud 1.76a
Danger: High - Crash bug in isolated instances
Found by: Samson
Fixed by: Samson

---

act_info.c, strip_crlf

Locate:
   static char newstr[MSL];
   int i, j;


Change to:
   static char newstr[MSL];
   int i, j;

   if( !str || str[0] == '\0' )
      return "";


This fix, much like the strip_cr fix before it, will prevent null strings from crashing the game. The strip_crlf function is not used in any data file saving currently so there is no danger in corrupting a file with this.
