diff,run



Hello,
My Maxima is 5.9.0 with CLISP 2.31, Mandrake 9.0
I encounter:
 >diff(sin(x),x,1); => dsin(x)
                             --
                             dx
>ev(%,diff); gives the same result.
>diff(sin(x),x,2); => will be evalueted as expexted
>printf(share.usg) =>
BREAK[1]>(run) => maxima restarts, but
> kill(all); => never returns!
How can I solve these awkwardnesses?
