--- Comment #3 from C. Masloch <pushbx at ulukai.org> ---
It seems that any trailing whitespace allows triggering the conditions for this
bug, eg:

$ cat test3.asm
%define MNCURRENT TEST  ; note comment/whitespace at end of line
%xdefine var MNCURRENT
$ 

If I understand it correctly, a %[...] construct that expands to "nothing"
actually results in a whitespace token, which is the reason it triggered the
bug.
