I'm trying to do an lto build of CP2K, but this fails with:

/data03/vondele/clean/cp2k/makefiles/../src/qs_linres_current.F: In function

Please submit a full bug report.

Not sure how to get a testcase for this one....

It appears to be for example this pointer assignment

my_gauge=>rs_gauge(1)%rs(igrid_level)%rs_grid%r

where 

REAL(dp), DIMENSION(:, :, :), POINTER    ::  my_gauge

and r is:

  TYPE realspace_grid_type

     REAL(KIND=dp), DIMENSION ( :, :, : ), ALLOCATABLE :: r   ! the grid

  END TYPE realspace_grid_type
