Bug ID: 103174
Summary: ICE in gfc_match_varspec, at fortran/primary.c:2154
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: ---
Started with r6 (valid, in contrast to pr95710) :
(line f = 'abc' is not neccessary to create an ICE)
$ cat z1.f90
module m
interface
module function f(x)
integer, intent(in) :: x
class(*), allocatable :: f
end
end interface
end
submodule(m) m2
contains
module function f(x)
integer, intent(in) :: x
class(*), allocatable :: f
f = 'abc'
end
end
$ gfortran-12-20211107 -c z1.f90
