Bug ID: 103589
Summary: ICE in gfc_match_varspec, at fortran/primary.c:2551
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: ---
Affects versions down to at least r5 :
(valid z2 works, but not the stripped one)
$ cat z1.f90
integer(size([character::'1'])) :: a
end
$ cat z2.f90
program p
integer(size([character::'1'])) :: a
a = 1
end
$ gfortran-12-20211205 -c z1.f90
