Comment #9 on issue 3512 by [email protected]: solve is slow for a simple
set of equations.

I don't think it's simplify that is causing the problem. I modified the
code and sent a symbolic matrix where every non-zero element in the matrix
to be solved is replaced with a dummy and all simplification is shut off
and it still hangs. The matrix looked like this:
[_19, _20, 0, 0, 0, _21, 0, 0, _22]
[_23, _24, 0, 0, 0, _25, _26, _27, _28]
[ 0, 0, 0, _29, _30, 0, 0, 0, _31]
[ 0, 0, 0, _32, _33, _34, 0, 0, _35]
[ 0, _36, 0, 0, 0, 0, _37, _38, _39]
[_40, _41, 0, _42, 0, _43, 0, _44, _45]
[ 0, _46, 0, 0, 0, _47, _48, _49, _50]
