Bug ID: 102417
Summary: Wrong error message about character length with
-std=f2018
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: ---
An embedded AC together with option -std=f2018 (or f2008 etc.)
produces a misleading error message. Typespec is explicitly given.
Affects versions down to at least r5.
That unique error message comes from line 1888 in decl.c.
Issue is eventually related to pr102315.
$ cat z1.f90

y = [[character(4) :: x, 'b', 'c']]
