compressed unreduced testcase

fault.c: In instantiation of ‘bool
clang::RecursiveASTVisitor<Derived>::TraverseAttr(clang::Attr*) [with Derived =
{anonymous}::ParentMapASTVisitor]’:
fault.c:201526:9:   required from ‘bool
clang::RecursiveASTVisitor<Derived>::TraverseDecl(clang::Decl*) [with Derived =
{anonymous}::ParentMapASTVisitor]’
fault.c:217418:53:   required from here

       return getDerived().TraverseNoSanitizeAttr(cast<NoSanitizeAttr>(A));
                                                  ~~~~~~~~~~~~~~~~~~~~^~~

attached testcase is from current clang git head, unreduced.

7.3.1 is unaffected for instance.
