Bug #: 53566
Summary: void template parameters are accepted if they result
from substitution
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: M8R-gt1qwe@spamherelots.com
GCC incorrectly accepts the following program (-std=c++11 -Wall -Wextra
-pedantic):
#include <type_traits>
template <typename T,
typename std::enable_if<std::is_reference<T>::value>::type...>
void f() {}
template <typename T,
typename std::enable_if<!std::is_reference<T>::value>::type...>
void f() {}
int main() {
f<int>();
f<int&>();
}
It should not accept it because substitution results in a void... template
parameter pack, which is not allowed.
