Bug ID: 64589
Summary: Undefined reference to integer 4 with unlimited
polymorphism in two modules plus main
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: damian at sourceryinstitute dot org
Using unlimited polymorphism appears to generate a linking error due to an
unrecognized integer symbol:
$cat more-fun-with-unlimited-poly.f90
module ASTG_FormatParser_mod
contains
subroutine fmt()
class(*), pointer :: arg
select type (arg)
type is (integer)
end select
end subroutine
end module
module ASTG_MpiFileHandler_mod
contains
subroutine makeString(arg1)
class(*) :: arg1
end subroutine
subroutine getSuffix()
use ASTG_FormatParser_mod
call makeString(1)
end subroutine
end module
end
$gfortran more-fun-with-unlimited-poly.f90
/tmp/cccnDYiT.o: In function `__astg_mpifilehandler_mod_MOD_getsuffix':
