One example is in src/ifs/phys_ec/local_state_ini.F90:

PT ! here a pointer to an input argument is assigned and returned in an output argument |
When the dummy argument is declared with an explicit size (as in the function above), it is system-dependent whether or not pointers associated with the dummy argument are valid after the subroutine finishes.
