            Bug ID: 42248
           Summary: ICE  when bool is #defined/typedef'd
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: zhonghao at pku.org.cn

My clang is 9.0.0, and the code is:

typedef bool _Bool;
# define bool _Bool

#include <vector>
#include <iostream>
#include <cstring>
using namespace std;

class Test : public vector<string> {
public:
 Test (Test& that) {
 arr = std::move(that.arr);
 }
private:
 std::vector<int*> arr;
};

It triggers an ICE:
