Bug ID: 65382
Summary: pointer-to-noexcept-function typealias allowed via
using
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vgheorgh at gmail dot com
According to 15.4 Exception specifications [except.spec]/2, the following code
should be rejected,
#include <iostream>
using fptr = void(*)() noexcept; // should not be accepted
// typedef void (*FPTR)() noexcept; // rejected by the compiler
void f() noexcept
{
std::cout << "void f() noexcept" << std::endl;
}
int main()
{
fptr fp = f;
fp();
}
Replacing using with a typedef makes the compiler emit an error, however the
code above compiles just fine, and it shouldn't.

But C++17 removed that restriction. The question becomes how important is this now the restriction is gone in new C++ standard and GCC moved to C++17 by default already. ^ permalink raw reply [flat|nested] 7+ messages in thread
