With the code:
----
#include <vector>

namespace rtc {

  bool Assert(bool result, const char* function) {
    return result;
  }

#define ASSERT(x) \
  (void)rtc::Assert((x), __FUNCTION__)




template<typename T>
class R {

  T ComputeMax() const {
    int i=0;
    ASSERT(count_ > 0 &&
	   "foo");
    max_ = std::max(2, samples_[samples_.size()]);
  }



  int count_;
  mutable T max_;
  std::vector<T> samples_;

};

}

building with clazy crashes clang

This is a reduce test case when building Firefox with clazy. It fails on webrtc code.

It is using Debian packages of clang. The same occurs with clang 3.6

Reproducible: Always
