Bug ID: 101728
Summary: ICE in initialize_inlined_parameters, at
tree-inline.c:3644
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Code with a potential name conflict (interface s
versus contained subroutine s, but ifort/ifx accepts it)
affects versions down to at least r5, at -O1+ :
$ cat z1.f90
module m
implicit none
interface s
subroutine g
end
end interface
contains
subroutine u
call s
end
subroutine v
integer :: n
n = 1
call s
contains
subroutine s
n = 2
end
end
end
$ gfortran-12-20210801 -c z1.f90
$
$ gfortran-12-20210801 -c z1.f90 -O1
during IPA pass: inline
z1.f90:9:12:
9 | call s
