<pre>My clang is 9.0.0, and the code is:
template<int n>
class mylist
{
public:
static int result[] = { mylist<n-1>::result };
};
clang accepts the code, but gcc reject it:
error: in-class initialization of static data member ‘int mylist<n>::result []’
of incomplete type
static int result[] = { mylist<n-1>::result };
^~~~~~
I tried to remove static, and the code is modified to:
template<int n>
class mylist
{
public:
int result[] = { mylist<n-1>::result };
};
In this case, gcc accepts it, but clang rejects it:
error: array bound cannot be deduced from an in-class initializer
int result[] = { mylist<n-1>::result };
^
1 error generated.
Both compilers accept the following code:
template<int n>
class mylist
{
public:
int result[1] = { mylist<n-1>::result };
};
This can be a bug in clang?</pre>
