No, I was mistaken. Everything can be traced back to g_gcd, which is called in sage.symbolic.expression.Expression.gcd. At that point, I lost track: I can not find the code of g_gcd (even "grep g_gcd" does not give me a hint). In particular, I did not change g_gcd, but it seems that my patch had a side effect on it. So, I am afraid I still need more insight!
