Bug ID: 82205 Summary: parametrized derived types, problems with initialization Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: physiker at toast2 dot net Target Milestone: --- gfortran-8 rejects the code bug3.f90. I believe it is legal, though. ifort version 17 compiles the code without a warning. The executable prints the expected output, when run. bug3.f90 module mod implicit none integer, parameter :: dp = kind (0.0d0) type, public :: v(z, k) integer, len :: z integer, kind :: k = kind(0.0) real(kind = k) :: e(z) end type v end module mod program bug use mod implicit none integer :: i type (v(2)) :: a type (v(z=:, k=dp)), allocatable :: b real :: c(2) = [ (1.5*i, i=1,size(c)) ] a = v(2)(c) b = v(2,dp)(c) print *, size(a%e), a%k print *, size(b%e), b%k end program bug LANG=C gfortran-8 -v -o bug3 bug3.f90 -W -Wall Driving: gfortran-8 -v -o bug3 bug3.f90 -W -Wall -mmacosx-version-min=10.11.0 -asm_macosx_version_min=10.11 -l gfortran -shared-libgcc Using built-in specs.
