            Bug ID: 89939
           Summary: messages for translation must not contain embedded
                    macro parameters
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: translation
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roland.illig at gmx dot de
  Target Milestone: ---

from fortran/frontend-passes.c:

#define B_ERROR(n) _("Incorrect extent in argument B in MATMUL intrinsic in " \
                     "dimension " #n ": is %ld, should be %ld")

#define C_ERROR(n) _("Array bound mismatch for dimension " #n " of array " \
                     "(%ld/%ld)")

In the .pot file, this results in:

msgid "Array bound mismatch for dimension "
msgstr ""

This translation entry will never be used. The part after the #n doesn't make
it to the .pot file at all.

Please write a linter that prevents this kind of bug. It's not the first time
I've seen it, and I don't want to remind you every year.
