Bug ID: 122696
Summary: [PDT] ICE when selector is a generic interface with
the same name as a derived type
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: damian at archaeologic dot codes
Target Milestone: ---
The reproducer was isolated with the pr 122693 because I think the current pr
one demonstrates a distinct issue because this issue occurs in the main
program, whereas in the case of 122693, moving the executable statements from
the function to the main program eliminates the problem demonstrated in 122693.
$ cat reproducer.f90
module tensor_m
implicit none
type tensor_t(k)
integer, kind :: k = kind(0.)
end type
interface tensor_t
module function tensor()
implicit none
type(tensor_t) tensor
end function
end interface
end module
use tensor_m
implicit none
associate(t => tensor_t())
end associate
end
$ gfortran -c reproducer.f90
reproducer.f90:19:28:
19 | associate(t => tensor_t())
