Bug ID: 89366
Summary: Fails to compile BIND(C) interface with assumed-length
character argument
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

test code
The extensions in C interop imply that an assumed-length character dummy
argument can appear in a BIND(C) interface, and is mapped to a C descriptor.
However, the attached test code fails to compile with the following error
message:
assumed_length_01_pos.f90:12:35:
12 | subroutine process_string(this, ierr) BIND(C)
| 1
Error: Character argument ?this? at (1) must be length 1 because procedure
?process_string? is BIND(C)
