Bug ID: 86111
Summary: ICE in gfc_arith_concat, at fortran/arith.c:985
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
With invalid code, down to at least gfortran 4.8 :
$ cat z1.f90
program p
character(2) :: c = 'a' // [character :: [1]]
end
$ cat z2.f90
program p
real :: c = 'a' // [character :: [1]]
end
$ cat z3.f90
program p
character(2) :: c = 'a' // [character :: 1.0]
end
