Memory leak with Eigen sparse matrices multiplication

Question

I have these three sparse matrices, defined in the following way:

typedef SparseMatrix<double> SpMat;

int m_totSize = 256*256;

SpMat *L = new SpMat(m_totSize, m_totSize);
SpMat *A = new SpMat(m_totSize, m_totSize);     
SpMat *W = new SpMat(m_totSize, m_totSize);

I am setting L with "setFromTriplets" and set W as the identity matrix.

Now I want to do:

*A = (*W)*(*L);

(Although I know it's going to give me L back).

And then:

delete L;
delete A;
delete W;

Even though I'm deleting the matrices at the end (I've also tried resize(0,0)), I'm experiencing severe memory leaks because of this multiplication.

Any ideas?

Thanks!

It seems the memory leak originates from another part of my application, and the multiplication is the final straw (in terms of memory consumption). But it does not originate from there... sorry.
