Bug ID: 89708
Summary: printf and std::byte
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: david.bolvansky at gmail dot com
Target Milestone: ---
#include <stdio.h>
#include <cstddef>
typedef unsigned char byte_t;
void test (byte_t a, std::byte b)
{
printf("%u", a); // OK
printf("%hhu", a); // OK
printf("%u", b); // GCC warns, Clang warns and recommends %hhu
printf("%hhu", b); // GCC warns
}
What is wrong with this code? I think we shouldn't see any warnings for
std::byte.. or?
