HP35S: a new 2*2 solve bug?

[BINUBALL]

There is thread discussing the problem. And also I can reproduce error with simulator.

Quote:It appears that registers G...L are used internally in the 2*2 lin. solve in an unusual way. If there is anything other than a real number in these registers (a complex number or a vector) the linear solver returns "no solution." Kind of interesting, as these registers are not overwritten after using the linear solver, which appears to indicate that these registers are not actually used.
