--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> ---
This is another instance of the mismatched built-in signature problem. With
-Wextra GCC 9 prints:
warning: mismatch in return type of built-in function ‘sprintf’; expected
‘int’ [-Wbuiltin-declaration-mismatch]
1 | unsigned int sprintf (char *str, const char *fmt, ...);
As we discussed, having the warning for the declaration disable treating the
function as a built-in will avoid these bugs.
