    inlined from 'pango_language_get_scripts' at ../pango/pango-language.c:661:21:
../pango/pango-language.c:518:12: error: array subscript 0 is outside array bounds of 'const void *[0]' {aka 'const void *[]'} [-Werror=array-bounds=]
  518 |     *cache = result;
      |     ~~~~~~~^~~~~~~~

+
+gcc has strange issues with this and produces false
+positives that recently started breaking the build of
+pango as a subproject in gtk.
+
+See e.g. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105523
