Bug ID: 102312
Summary: [12 Regression] ICE in gfc_get_dtype_rank_type, at
fortran/trans-types.c:1558
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
Changed between 20210530 and 20210606 :
$ cat z1.f90
program p
print *, f(null())
contains
integer function f(x) bind(c)
use iso_c_binding
integer(kind=c_int), pointer, intent(in) :: x(..)
f = 0
end
end
$ cat z3.f90
recursive function f(x) result(z) bind(c)
use iso_c_binding
integer(kind=c_int), pointer, intent(in) :: x(..)
real :: z
z = f(null())
end
$ gfortran-11 -c z1.f90
