           Summary: [10/11 Regression] ICE in gfc_get_class_from_expr, at
                    fortran/trans-expr.c:484

           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Changed between 20190922 and 20190929 :


$ cat z1.f90
program p
   type t
   end type
contains
   function f() result(x)
      class(t), allocatable :: x
      associate (y => (f))
      end associate
   end
end


$ gfortran-9 -c z1.f90   # no error

    7 |       associate (y => (f))
      |                       1
Warning: Non-RECURSIVE procedure 'f' at (1) is possibly calling itself
recursively.  Declare it RECURSIVE or use '-frecursive'
