Compilation Error with GCC 9.1.0

There are extra checks with GCC 9.1.0 that need addressing:

common_io.c: In function 'io_check_output_fields':
common_io.c:1808:43: error: '%s' directive writing up to 43199 bytes into a region of size 1011 [-Werror=format-overflow=]
 1808 |         sprintf(field_name, "SelectOutput:%s_%s", list[field_id].name,
      |                                           ^~
common_io.c:1808:9: note: 'sprintf' output 15 or more bytes (assuming 43214) into a destination of size 1024
 1808 |         sprintf(field_name, "SelectOutput:%s_%s", list[field_id].name,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 1809 |                 part_type_names[ptype]);
      |                 ~~~~~~~~~~~~~~~~~~~~~~~

single_io.c: In function 'write_output_single':
single_io.c:1154:36: error: '%s' directive writing up to 43199 bytes into a region of size 243 [-Werror=format-overflow=]
 1154 |       sprintf(field, "SelectOutput:%s_%s", list[i].name,
      |                                    ^~
single_io.c:1154:7: note: 'sprintf' output 15 or more bytes (assuming 43214) into a destination of size 256
 1154 |       sprintf(field, "SelectOutput:%s_%s", list[i].name,
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 1155 |               part_type_names[ptype]);
      |               ~~~~~~~~~~~~~~~~~~~~~~~

I think it's just a case of lengthening the string.
