Bug ID: 96024
Summary: [9/10/11 Regression] ICE in mio_name_expr_t, at
fortran/module.c:2159
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
This invalid code (character char(n) is not a legal len value)
gives an ICE down to r6, seems to be accepted by r5 :
$ cat z1.f90
module m
type t
character(char(1)) :: a
end type
type(t) :: z = t('a')
end
$ gfortran-5 -c z1.f90
$
$ gfortran-11-20200628 -c z1.f90
