            Bug ID: 92482
           Summary: Possibly wrong error diagnostic
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jrfsousa at gmail dot com
  Target Milestone: ---

Created attachment 47225
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47225&action=edit
Code demonstrating problems.

What seems to me a spurious error is flagged by gfortran 10.0.0 20191106:

Error: Character argument ‘this’ at (1) must be length 1 because procedure
‘strg_print_0’ is BIND(C)

Gfortran 9.1.0 also issues a warning and the code generated raises a
segmentation fault:

Warning: ‘.this’ may be used uninitialized in this function
[-Wmaybe-uninitialized]

I may be missing the something in the standard but I see no clause demanding 
this behavior and it is used on C.12.14 Mapping of MPI interfaces to Fortran.

Thank you very much.

Best regards,
