That is indeed a bit silly. It really does seem to require that the application (using this API) quits or crashes. I suppose you should warn the user that a fatal error happened and quit Glom. Hopefully it’s very very rare, and there’s no point worrying too much about something that isn’t going to happen.

You might also try to find out who added that function (by looking at a ChangeLog, for instance), and ask him. But I’d leave it until later, if at all.

/* Write an in-memory PO file to a file.
Upon failure, return NULL and set errno. */
#define po_file_write po_file_write_v2
extern po_file_t po_file_write (po_file_t file, const char *filename,
po_xerror_handler_t handler);
