[cfe-commits] [Patch][review-request]Fix for 'using namespace' within function body in static analyzer

[Jim Goodnow II]

The following code, when compiled with 'clang -cc1 -analyze 
-analyzer-check-objc-mem -cfg-dump' will generate a 'Subtype of 
ScopeDecl not handled error', I'm not sure where a test case should 
go for this?

namespace fum {
   int i = 3;
};

void foo() {
   using namespace fum;

   int x = i;
}
