--- Comment #2 from Jürgen Reuter <juergen.reuter at desy dot de> --- This is our unit test, we now confirmed that this is the only problem, so the only failing test: it really looks like that the finalizer for the subroutine crashes, all routines inside the subroutine get executed correctly: subroutine simulations_10 (u) integer, intent(in) :: u type(string_t) :: libname, procname1, expr_text type(rt_data_t), target :: global type(rt_data_t), dimension(1), target :: alt_env type(ifile_t) :: ifile type(stream_t) :: stream type(parse_tree_t) :: pt_weight type(simulation_t), target :: simulation type(event_sample_data_t) :: data write (u, "(A)") "* Test output: simulations_10" write (u, "(A)") "* Purpose: reweight event" write (u, "(A)") write (u, "(A)") "* Initialize processes" write (u, "(A)") call syntax_model_file_init () call syntax_pexpr_init () call global%global_init () call global%set_log (var_str ("?omega_openmp"), & .false., is_known = .true.) call global%set_int (var_str ("seed"), & 0, is_known = .true.) libname = "simulation_10a" procname1 = "simulation_10p" call prepare_test_library (global, libname, 1, [procname1]) call compile_library (libname, global) call global%append_log (& var_str ("?rebuild_phase_space"), .true., intrinsic = .true.) call global%append_log (& var_str ("?rebuild_grids"), .true., intrinsic = .true.) call global%append_log (& var_str ("?rebuild_events"), .true., intrinsic = .true.) call global%set_string (var_str ("$method"), & var_str ("unit_test"), is_known = .true.) call global%set_string (var_str ("$phs_method"), & var_str ("single"), is_known = .true.) call global%set_string (var_str ("$integration_method"),& var_str ("midpoint"), is_known = .true.) call global%set_log (var_str ("?vis_history"),& .false., is_known = .true.) call global%set_log (var_str ("?integration_timer"),& .false., is_known = .true.) call global%set_log (var_str ("?recover_beams"), & .false., is_known = .true.) call global%set_real (var_str ("sqrts"),& 1000._default, is_known = .true.) call global%it_list%init ([1], [1000]) call global%set_string (var_str ("$run_id"), & var_str ("simulations1"), is_known = .true.) call integrate_process (procname1, global, local_stack=.true.) write (u, "(A)") "* Initialize alternative environment with custom weight" write (u, "(A)") call alt_env(1)%local_init (global) call alt_env(1)%activate () expr_text = "2" write (u, "(A,A)") "weight = ", char (expr_text) write (u, *) call ifile_clear (ifile) call ifile_append (ifile, expr_text) call stream_init (stream, ifile) call parse_tree_init_expr (pt_weight, stream, .true.) call stream_final (stream) alt_env(1)%pn%weight_expr => pt_weight%get_root_ptr () call alt_env(1)%write_expr (u) write (u, "(A)") write (u, "(A)") "* Initialize event generation" write (u, "(A)") call global%set_log (var_str ("?unweighted"), & .false., is_known = .true.) call simulation%init ([procname1], .true., .true., global, alt_env=alt_env) call simulation%init_process_selector () data = simulation%get_data () call data%write (u) write (u, "(A)") write (u, "(A)") "* Generate an event" write (u, "(A)") call simulation%generate (1) call simulation%write (u) write (u, "(A)") write (u, "(A)") "* Write the event record for the last event" write (u, "(A)") call simulation%write_event (u) write (u, "(A)") write (u, "(A)") "* Write the event record for the alternative setup" write (u, "(A)") call simulation%write_alt_event (u) print *, "written alt_event, starting cleanup ..." write (u, "(A)") write (u, "(A)") "* Cleanup" call simulation%final () print *, "simulation finalized" call global%final () print *, "global finalized" call syntax_model_file_final () print *, "syntax_model_file finalized" call syntax_pexpr_final () print *, "syntax pexpr finalized" write (u, "(A)") write (u, "(A)") "* Test output end: simulations_10" end subroutine simulations_10
