I am not able to reproduce your problem. In both ECLiPSe 5.10 or 5.11, I 
get success with the query b(b,1). [after correcting a syntax error in 
your definition of tra/2]

How did you produce your execution from ECLiPSe? There is a syntax error 
in tra/2 (missing ')'); and various messages from ECLiPSe are missing, 
and the yes and no are not exactly what recent versions of ECLiPSe prints.

Here is what I get:
[eclipse 1]: [user].
tra(a(a,A),b(b,A)).
:- local macro(a/2,tra/2,[term]).
user compiled traceable 132 bytes in 0.00 seconds

Yes (0.00s cpu)
[eclipse 2]: [user].
a(a,1).
user compiled traceable 40 bytes in 0.00 seconds

Yes (0.00s cpu)
[eclipse 3]: b(b,1).

Yes (0.00s cpu)
