danglingTemporaryLifetime False positive

[Julien]

Hello,

Thanks a lot for your awesome project. I think I've found a false positive for danglingTemporaryLifetime warning:

#include <iostream>
#include <vector>

std::vector<int> ints = {0, 1, 2, 3};

int main() {
  auto *ptr = &ints;
  if (rand() / 2 == 0) {
    ptr = &ints;
  }
  for (auto it = ptr->cbegin(); it != ptr->cend(); ++it) { // Using iterator to temporary.
    std::cout << *it << "\n";                               // Using iterator to temporary.
  }
  return 0;
}

Removing the if block removes the warning. Changing the condition to something more predictable (e.g. true) removes the warning. I'm not sure why such code should trigger a warning.

Thanks again for your project.
