ifort with mkl and function mkl_sparse_d_mv

I compile my program and it gives the following error:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

I isolated the problem and it is occurring at the call of the mkl_sparse_d_mv function of the following function:

function dVdt(self, t, V)
        class(MotorUnitPool), intent(inout) :: self
        real(wp), intent(in) :: t
        real(wp), intent(in) :: V(:)
        real(wp), dimension(self%totalNumberOfCompartments) :: dVdt
        integer :: i, j, stat
        real(wp), dimension(:), allocatable :: matInt

        allocate(matInt(self%totalNumberOfCompartments))
              
        do i = 1, self%MUnumber
            do j = 1, self%unit(i)%compNumber
                self%iIonic((i-1)*self%unit(i)%compNumber+j) = self%unit(i)%Compartments(j)%computeCurrent(t, V((i-1)*self%unit(i)%compNumber+j))
            end do
        end do       
        
        stat = mkl_sparse_d_mv(self%spOperation, &
                                                self%spAlpha, &
                                                self%GSp, &
                                                self%spDescr, &
                                                V, &
                                                self%spBeta, &
                                                matInt)
        
        dVdt = (self%iIonic + matInt + self%iInjected + self%EqCurrent_nA) * self%capacitanceInv       
end function

I compile with gfortran without any problems. As compiler options to the ifort compiler i tried to use the option -heap_arrays, whith no success.

This function is part of a bigger program, with some files. If you want to see the whole software, you can find it in https://github.com/rnwatanabe/projectFR .
