用gdb调试Fortran程序，如何查看派生类型数据？
例如，查看ndim就可以直接输入： p data%ndim但是要查看coorn里的数据是什么命令呢？ coorn是动态分配的数组
我输入 p data%coorn 提示 =<object is not allocated>
但是coorn明明已经分配好内存了

!   test2.f90
program main
        use comm_data
        implicit none
        type(core_data) :: data


        call allo_core_data( data, 2, 4)
        data % coorn = 4.0

        write(*,*) data % coorn

        stop
end program main

! comm_data.f90
module comm_data
        implicit none
        
        save
        
        type core_data                
                integer ndim                
                integer npoint
                real,    allocatable, dimension(:,:) :: coorn                
        end type core_data        
        
        contains

subroutine allo_core_data(        data, ndim, npoint )
        implicit none
        type(core_data), intent(out) :: data
        integer, intent(in) :: npoint
        integer, intent(in) :: ndim
        
        data % ndim = ndim
        data % npoint = npoint
        
        allocate( data % coorn( data % ndim, data % npoint ) )
        data % coorn = 0.0
        
end subroutine allo_core_data


end module comm_data
