Eigen crash for SparseMatrix when using conservativeResize and block expressions

Link to original bugzilla bug (#563)
Version: 3.2
Description
The following code segfaults on the latest Eigen development branch:
////////////////////////////////////////////////////////
#include <Eigen/Sparse>
using namespace Eigen;
int main()
{
SparseMatrix<double> A(3, 3);
for (int i = 0; i < 3; ++i)
A.insert(i,i) = 1.0;
A.conservativeResize(3, 4);
A.col(3) = A.col(2); }
////////////////////////////////////////////////////////
I understand this is still beta-level functionality, so take this bug report as you will.
