bug in solve/algsys (0 is not of type LIST)



Hello,

When I try this I get an error:

sys:[b2 + a1 = r2, a1 * b2 = r3, a2 * b2 + a3 * b1 = r4, a3 * b2 + a5 + r4 = d5, a5 * b1 = 0];
solve(sys, [a1, a2, a3, a5, r2, r3, r4, b1, b2]);

Error in MACSYMA-TOP-LEVEL [or a callee]: 0 is not of type LIST.

This bug exists at least from 5.9.0 version.
I use actually 5.10.0.a on WinXP
