function
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++11

Complete log
The following code does not compile with clang r193986 and libc++ r193989, even
though it compiled successfully with clang r193515:
#include <functional>
template <typename F>
static void foo(F f)
{
std::function<void()> func = f;
}
int main()
{
foo([]() {});
}
This results in (complete log attached):
