I do not see that Maple version 13.00 fail on it, using the 64bit Linux install.

I see this success below, after a fresh `restart`, and have not yet seen it fail after trying in several fresh kernel sessions.

  restart:

  kernelopts(version);

            Maple 13.00, X86 64 LINUX, Apr 13 2009, Build ID 397624

  assume(0<d,d<1);

  int(cos(theta)*sin(theta)/(1+d*cos(theta))^3,theta=0..Pi);

                                      2 d~
                     - ----------------------------------
                              2                        2
                       (1 + d~  + 2 d~) (-2 d~ + 1 + d~ )


Is it possible that you have something in your initialization file (~/.mapleinit), and did not launch with the -s option to suppress use?

Or perhaps you have some custom .mla archive in `libname` and some value for a global name is being picked up from there?
