<pre>This shouldn't warn:
$ cat test.cc
class ScriptData {
public:
virtual ~ScriptData() { }
virtual bool HasError() = 0;
};
void operator delete[](void* ptr) throw();
void operator delete(void* ptr) throw();
But it does:
$ third_party/llvm-build/Release+Asserts/bin/clang -c test.cc -std=gnu++11
-Wall
test.cc:7:6: warning: function previously declared with an implicit exception
specification redeclared with an explicit exception specification
[-Wimplicit-exception-spec-mismatch]
void operator delete[](void* ptr) throw();
^
test.cc:8:6: warning: function previously declared with an implicit exception

[-Wimplicit-exception-spec-mismatch]
void operator delete(void* ptr) throw();
^
