Analyze precompiled C++ files with Frama-C

Question

I'm trying to analyze some pre-compiled C++ files (.ii) using Frama-C. I know it has many limitations, but my problem has to do with compilation errors which I think are related to the clang compiler. I'm using Frama-21.0 and clang-0.0.9.

I'm using the example I found in this issue but including the vector library, because I needed for my other files.

#include <exception>
#include <vector>

class empty_stack: public std::exception {
  virtual const char* what() const throw() {
    return "stack is empty!";
  }
};

class full_stack: public std::exception {
  virtual const char* what() const throw() {
    return "stack is full!";
  }
};

template <class T>
class Stack {
private:
  T elems[10];
  unsigned index;
public:
  Stack() {
    index = 0;
  }
  void push(T const&);
  T pop();
  T top() const;
  bool empty() const {
    return index == 0;
  }
};

template <class T>
void Stack<T>::push (T const& elem) {
  if (index >= 10) throw new full_stack();
  elems[index++] = elem;
}

template <class T>
T Stack<T>::pop () {
  if (index == 0) throw new empty_stack;
  return elems[--index];
}

template <class T>
T Stack<T>::top () const {
  if (index == 0) throw new empty_stack;
  return elems[index-1];
}

int main() {
  try {
    Stack<int> intStack;
    intStack.push(7);
    intStack.push(42);
    return intStack.pop();
  } catch (char* ex) {
    return -1;
  }
}

So I am able to compile and pre-compile the file using Clang-9 with these command:

clang++ -std=c++17 -stdlib=libc++ data/example.cpp -o example

clang++ -std=c++17 -stdlib=libc++ data/example.cpp -E > data/example.ii

But then, when I try to analyze the files with frama-c, with this command:

frama-c data/example.ii -cxx-c++stdlib-path /usr/local/clang_9.0.0/include/c++/v1 -deps > logFiles/example.log

I get this:

[kernel] Parsing data/example.ii (external front-end)
[kernel] User Error: Failed to parse C++ file. See Clang messages for more information
[kernel] User Error: stopping on file "data/example.ii" that has errors.
[kernel] Frama-C aborted: invalid user input.

And the Clang messages are like this:

Any suggestions?? Thanks in advance
