[Bug fortran/80361] [5/6/7/8 Regression] [OOP] bogus recursive call to nonrecursive procedure with -fcheck=recursion
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80361 Antoine Lemoine changed: What|Removed |Added CC||antoine.lemoine@bordeaux-in ||p.fr --- Comment #28 from Antoine Lemoine --- I was able to reproduce the runtime error with gfortran 9.3.0 and 10.1.0 using the following code: program test_recursive_call implicit none type t_tree_node type(t_tree_node), dimension(:), allocatable :: child end type type t_tree type(t_tree_node), allocatable :: root end type type(t_tree), allocatable :: tree allocate(tree) allocate(tree%root) allocate(tree%root%child(1)) ! If the line below is removed, the code works fine. allocate(tree%root%child(1)%child(1)) deallocate(tree) end program Command line to compile the code: gfortran -g -fcheck=recursion -o tree tree.f90 I obtain the following runtime error: At line 1 of file tree.f90 Fortran runtime error: Recursive call to nonrecursive procedure '__deallocate_test_recursive_call_T_tree_node' Error termination.
