Summary: algsys -- variable order dependent

Initial Comment:

 (%i1) algsys([z-a=%i*b,z+a=c,a*z+3*(a-z)=13-12*%i,3*(z-a)+a*z=12*%i+13],[a,c,b,z]);
 (%o1) []

 (%i2) algsys([z-a=%i*b,z+a=c,a*z+3*(a-z)=13-12*%i,3*(z-a)+a*z=12*%i+13],[z,a,c,b]);
 (%o2) [[z=2*%i-3,a=-2*%i-3,c=-6,b=4],[z=-(3*%i+11)/(%i-3),a=3-2*%i,c=6,b=4]]

I think this is a known bug. See ID: 1944012 - solve() fails depending on
equation order.
