Bug 370609

Compile the following code snippet with the bleeding edge clazy and clang 3.8 or 3.9:

clazy -std=gnu++11 -o example.cpp.o -c example.cpp

example.cpp:

#include <vector>

template <typename T>
struct Example
{
  Example()
  {
    for (auto sample : SampleCache)
    {
    }
  }

  std::vector<float> SampleCache;
};

void CreateExample()
{
    new Example<int>();
}



Reproducible: Always

Steps to Reproduce:
1.  Compile example.cpp with Clazy.


Actual Results:  
Crash.

Expected Results:  
Clazy should not crash.

The code compiles fine with clang, only Clazy crashes.
