Mathematica v. 4 correctly solves the following simple couple of linear
recurrences
RSolve[{Ts[k]==2Tp[k-1]+1, Tp[k]==2Tp[k-1]+Ts[k-1]+2,
Tp[0]==0,Ts[0]==0},{Ts[k],Tp[k]},k]
With Mathematica v.5 the computation enters a never ending loop.
I found this bug using Mac OS X 10.2.8 but the same happens on Windows
systems too.
Any hint?
