            Bug ID: 20996
           Summary: crash on invalid return of an object with a deleted
                    destructor
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Keywords: crash-on-invalid
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dblaikie at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

struct foo {
    foo(int);
    ~foo() = delete;
  };
  foo func() {
    return 1;
  }

Ends up calling clang::Expr::isTemporaryObject on a null Expr*.
