Today's bugs

[Richard B. Kreckel]

Consider this:
higgsino:~/projects/GiNaC/ginsh$ ./ginsh 
ginsh - GiNaC Interactive Shell (GiNaC V0.5.2)

Type ?? for a list of help topics.
> series(gamma(x),x,0,2); collect(series(gamma(x),x,0,2),x);
-EulerGamma+x*(1/12*Pi^2+1/2*EulerGamma^2)+x^(-1)+Order(x^2)
-EulerGamma+x*(1/12*Pi^2+1/2*EulerGamma^2)+x^2*Order(1)+x^(-1)

The other bug is with the fraction free elimination in ginac/matrix.cpp:
If I try to solve the system 
[[ [[0,2-a]], [[5-4*a,3+2*a]] ]] * [[ [[x]], [[y]] ]] 
                          == [[ [[-2+5*a]], [[-5-2*a]] ]]
I run into trouble within assert-blocks.  

I will have a look at the second problem.
                                      -rbk.
