Bug ID: 89841
Summary: improper descriptor information passed to C
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: Bader at lrz dot de
Target Milestone: ---

UNIX archive with test case
The attached archive contains a Fortran main program and a C source file. It
can be compiled with
gcc -c assumed_shape_01_pos.c
gfortran assumed_shape_01_pos.f90 assumed_shape_01_pos.o
Running the resulting executable shows a failure to properly pass the
descriptor information to C. Since the dummy arguments are declared
assumed-shape, that->attribute should have the value CFI_attribute_other even
if the actual argument is POINTER or ALLOCATABLE. Furthermore, the lower bounds
are also not remapped as is required for a CFI_attribute_other descriptor.
