<pre>Hi, all.
This code, test.cc, is an invalid code I guess, but Clang accepts this without
any diagnostic message.
$cat test.cc
class A {
template <class> void F(){};
template <> void F<int>();
};
I think explicit specialization shouldn't exist in a class definition.
While in other compilers:
Output in GCC:
test.cc:3:15: error: explicit specialization in non-namespace scope 'class A'
3 | template <> void F<int>();
| ^
test.cc:3:22: error: template-id 'F<int>' in declaration of primary template
3 | template <> void F<int>();
| ^~~~~~
Output in ICC:
test.cc: error: explicit specialization is not allowed in the current scope
template <> void F<int>();
^
Noted that this issue only happens in Clang-7 and onwards version, while other
version upwards Clang-6 rejects this with "error: explicit specialization of
'F' in class scope".
Thanks,
Haoxin</pre>
