  While extending the matrixwrapper test I noticed that although the product of a matrix with a symmetric matrix is not implemented (as far as I can see), the call doesn't result in an error during compilation nor execution when using LTI The test I used is: Matrix Csm_test = Am * As; where Am is a Matrix and As a SymmetricMatrix.

Cannot reproduce this with eigen, so it seems to be boost specific
