Are you sure that's it?  It looks like the code you posted is
referencing two different variables (if you just cut and pasted,
that is.)

According to your earlier post:

   include file treeview.ew
   global function filltvitem(atom Item, atom mask, atom state)
   .....<del code>.....
      txtbuff = myalloc(256)
   .....<del code>.....
      return txtbuff
   end function

And then you have:

   [ main program ]
   global atom txtbuf
   include treeview.ew
   .....<del code>.....
       itxtbuff = filltvitem(hItem, TVIF_TEXT, 0)
       item = SendMessage(id, TVM_GETITEM, 0, tvitem)
       path = {peek_zstring(txtbuff)}

Note that in treeview.ew, you reference atom <txtbuff>, and in
your main program you declare atom <txtbuf>.  You then attempt
to use atom <txtbuff> in your main code, but it has not been declared
yet, only atom <txtbuf> has.  It appears that you are using two different
atoms here, one with two trailing f's, and one with only a single trailing f.
If this is the case, version 2.2, 2.1, 1.5a etc will fail with an error as well.
