            Bug ID: 109105
           Summary: Error-prone format string building in resolve.cc
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: translation
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roland.illig at gmx dot de
  Target Milestone: ---

The function resolve_operator constructs a format string and then passes it to
gfc_error. This approach is wrong, and if a translator such as me makes a typo
in the translation, GCC can crash.

Instead of jumping to bad_op, each error must be handled individually, and the
messages to be translated must be marked as having format gcc-internal-format
or gfc-internal-format, not c-format.

--- Comment #1 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Can you give an example of what this one should look like?

              snprintf (msg, sizeof (msg),
                        _("Inconsistent ranks for operator at %%L and %%L"));
              goto bad_op;

Roland, where do we stand on this PR?

--- Comment #3 from Roland Illig <roland.illig at gmx dot de> ---
Nothing has changed yet.

There is no built-in validation in the translated messages that each '%%L' from
the msgid matches a '%%L' from the msgstr.

I suggest to replace the label 'bad_op' with a function named 'bad_op', so that
the format strings contain '%L' instead of the current '%%L', so that gettext
can validate the format strings in the translations.
