Bug ID: 87568 Summary: Gfortran compile fails with bogus error message. Product: gcc Version: 8.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: david.sagan at gmail dot com Target Milestone: --- consider the following test program: subroutine tao_show_this () implicit none type b_struct integer, pointer :: good_user => null() end type type a_struct type (b_struct), allocatable :: value_ptr(:) end type type (a_struct) a a = a_struct() end subroutine Compiling gives: > gfortran -c test.f90 test.f90:4:13: type b_struct 1 Error: The rank of the element in the structure constructor at (1) does not match that of the component (0/1) I believe this error message is bogus. Ifort will compile this code without error. Note: This code will compile if modified in a number of ways: 1) Replace "value_ptr(:)" with "value_ptr" as the allocatable component of a_struct. 2) Replace "integer, pointer :: good_user => null()" with "integer :: good_user = 0" as the component of b_struct. 3) Replace "a = a_struct()" with "a = a_struct(null())".
