Bug ID: 67245
Summary: static_assert on inline function gives an error
Product: gcc
Version: 4.9.2
URL: http://stackoverflow.com/questions/32045025/static-ass
ert-on-inline-function-gives-error
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eugene at hutorny dot in.ua
Target Milestone: ---
Created attachment 36193
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36193&action=edit
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

Oh looks like "weak" is getting in the way here.
