    Fixed BUG#13941: replace() string fuction behaves badly inside stored · a7f4882a

                     procedure
      For some functions returning strings (like "replace" and "ifnull" - where
      val_str() is returning a pointer into one of the parameters) - we ended
      up with a dangling pointer after the new operator destroyed the reuse item
      in the eval function.
      A working, if not very elegant, solution is to simply copy the string in
      such cases.

      Copy the string when evaluating some string functions (e.g. "replace" and "ifnull")
      to avoid using a dangling pointer.
