Bug ID: 88467 Summary: Silently accepts wrong array constructor Product: gcc Version: 9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: gs...@t-online.de Target Milestone: --- Extracted from pr88116. Silently accepts these array constructors and consequently prints wrong results : $ cat z1.f90 program p print *, [integer :: 1, [integer(1) :: '3', 4]] print *, [integer :: 1, [integer(2) :: '3', 4]] print *, [integer :: 1, [integer(8) :: '3', 4]] print *, [integer :: 1, [integer(16) :: '3', 4]] end $ cat z2.f90 program p print *, [integer :: 1, [integer(1) :: 2, '3']] print *, [integer :: 1, [integer(2) :: 2, '3']] print *, [integer :: 1, [integer(8) :: 2, '3']] print *, [integer :: 1, [integer(16) :: 2, '3']] end $ cat z3.f90 program p print *, [integer(8) :: 1, [integer(4) :: 2, '3']] end $ gfortran-9-20181209 z1.f90 -static-libgfortran $ a.out 1 0 4 1 0 4 1 0 4 1 0 4 $ gfortran-9-20181209 z3.f90 -static-libgfortran $ a.out 1 2 0 $
