Bug ID: 62227
Summary: Templated move not elided
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: roman.perepelitsa at gmail dot com
#include <stdio.h>
struct S {
S(int) {}
S(const S&) = default; // (1)
template <class = void> // (2)
S(S&& other) {
puts("move");
}
};
int main() {
S s = 42;
(void)s;
}
This program unexpectedly prints "move". The expected output is empty (move is
elided).
The program prints nothing (as expected) if any of the following is done:
- Line (1) is removed.
- Line (2) is removed.
- The program is compiled with clang.
