[eigen] Uninitialized memory?

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]



Dr. Memory gives me this error which seems to be in sparselu. Maybe it is a false positive.

         Error #1: UNINITIALIZED READ: reading 8 byte(s)
         Eigen::internal::pload<>
             e:\libraries\eigen\eigen-3.2.4\eigen\src\core\genericpacketmath.h(153):
         Eigen::internal::sparselu_gemm<>

I am calling:

                solver.factorize(matrixA);
