Link to original bugzilla bug (#835)
Version: 3.2

Description

The following does not compile:

Matrix3d A;
RowVector3d bT, xT;

A << 1, 2, 3,
4, 5, 6,
7, 8, 9;

bT << 1, 2, 3;

xT = A.triangularView<Upper>().solve<OnTheRight>(bT); // WORKS FINE!
printf("(%g, %g, %g)", xT(0), xT(1), xT(2));

SparseMatrix<double> spA = A.sparseView();
spA.triangularView<Upper>().solve<OnTheRight>(bT); // COMPILE ERROR!

SparseTriangularView::solve accepts neither <OnTheLeft> nor <OnTheRight> as template argument, but neglecting the argument compiles fine..

Depends on
