            Bug ID: 28666
           Summary: clang chrashes with -Wthread-safety in
                    clang::CFGImplicitDtor::getDestructorDecl
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
          Assignee: kremenek at apple.com
          Reporter: nand at fb.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The following example causes clang to chrash:

struct Holder {
  virtual ~Holder() throw() {}
  int i = 0;
};

int main() {
  const auto &value = Holder().i;
}

Due to incorrect handling of lifetime-extending constructs.
