            Bug ID: 103957
           Summary: ICE passing return value from elemental type bound
                    procedure
           Product: gcc
           Version: 9.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ffadrique at gmail dot com
  Target Milestone: ---

Created attachment 52149
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=3D52149&action=3Dedit
Type used for the type bound procedure

The attached code produces an ICE when compiled with 9.3.0 (my reference
compiler)
Does not occur with 10, 11 and 12.

The problem appears on the polymorphic array (elements) but not in the array
declared with type and fixed length. If the array is allocatable but not
polymorphic the issue does not occur either.


Compiler error follows:


fran@atlantis:~/tmp/passing_elemental$ gfortran Use.f03 Program.f03 -o
Program.bin=20
Program.f03:15:0:

   15 |   call check_array( elements%get_i() )
      |=20
internal compiler error: in gfc_conv_expr_descriptor, at
fortran/trans-array.c:7348
Please submit a full bug report,
with preprocessed source if appropriate.
