<div>
<pre>While compiling the following code in C++98 or C++03 (not in C++11) mode Clang
produces an error:
template <int> struct A {};
int const i = { 42 };
typedef A<i> Ai;
The error:
test.cpp:4:11: error: non-type template argument of type 'int' is not an
integral constant expression
typedef A<i> Ai;
^
test.cpp:4:11: note: initializer of 'i' is not a constant expression
test.cpp:3:11: note: declared here
int const i = { 42 };
^
As far as I understand "i = 42" and "i = { 42 }" should be equivalent and
should produce no error.
The following code compiles without problems:
int const j = 42;
typedef A<j> Aj;</pre>
