I think there is a bug in CAS mode using "zeros", "solve"

solve ((-e)^x*(-cos(x)+sin(x))=0,x) returns {1/4*pi, 5/4*pi}.

Yes, but I also use diff(e^x*cos(x),x) inside program and the differentiation gives me e^x*cos(x)-e^x*sin(x) and when I want zeros I get the same error so parenthesis will not solve my problem. Thanks.
