Bug ID: 67245
Summary: static_assert on inline function gives an error
Product: gcc

code snippet
Consider the following example
<code>
typedef void (*foo)();
template<foo f>
struct bar {
static_assert(f!=nullptr,"f == null!");
};
void baz() {}
inline void bax() { }
bar<baz> ok;
bar<bax> bad; // error: non-constant condition for static assertion
<code>
When compiled with (g++ -std=c++14) compilation fails with
error non-constant condition for static assertion,
blaming bax to be non-constant.
This example compiles well in clang++ 3.7 and VC++ 14.0
