Bug ID: 65994
Summary: auto deduces object instead of initializer_list
Product: gcc
Version: 5.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Consider the following:
struct Foo{};
int main()
{
Foo a;
auto b{a};
a = b;
}
The code compiles because b gets deduced as Foo instead of
std::initializer_list<Foo>. This new deduction rule is proposed in N3922 for
C++1z but is not yet part of the standard, yet gcc still apparently interprets
it that way (with either -std=c++11 or -std=c++14). While N3922 indicates that
deducing b as std::initializer_list<Foo> is a defect in C++14, it still is in
C++14.
