--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks for filing this bug.
Notes to self: warning is emitted by convert_escape in libcpp/charset.c:1466
here:
1461 /* diagnostic.c does not support "%03o". When it does, this
1462 code can use %03o directly in the diagnostic again. */
1463 char buf[32];
1464 sprintf(buf, "%03o", (int) c);
1465 cpp_error (pfile, CPP_DL_PEDWARN,
1466 "unknown escape sequence: '\\%s'", buf);
when first parsing the string token, via cpp_interpret_string, and so
loc_readers is NULL.
