Test code to reproduce the issue
The following code compiles with Clang bundled with Xcode 5.0 but produces an
error with Clang trunk:
#include <stdio.h>
namespace MyNamespace
{
class MyClass
{
public:
MyClass() { }
~MyClass() { }
};
}
class MyNamespace::MyClass;
int main()
{
fprintf(stderr, "Test code to reproduce an issue when compiling with Clang
trunk\n");
return 0;
}
When compiling this file by performing the command
clang -o test test.cpp
you will see the error:
test.cpp:14:7: error: forward declaration of class cannot have a nested name
specifier
class MyNamespace::MyClass;</pre>
