including visualizer header causes segfault with clang tidy

Your Environment

• Operating System and version: Ubuntu 18.04
• Compiler: GCC 7
• PCL Version: Latest

Context

Please see below minimal code to reproduce the problem

CMakeLists.txt

cmake_minimum_required(VERSION 3.11)

project(sample)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall")

find_package(PCL REQUIRED)

add_executable(${PROJECT_NAME} main.cpp)

target_link_libraries(${PROJECT_NAME} ${PCL_LIBRARIES})

main.cpp

#include "pcl/visualization/pcl_visualizer.h"

int main() {
  int a; // this is needed to trigger the segfault along with including pcl_visualizer.h

  return 0;
}

After mkdir build && cd build and then cmake "-DCMAKE_CXX_CLANG_TIDY=clang-tidy" ..

make yields

[ 50%] Building CXX object CMakeFiles/sample.dir/main.cpp.o
Error running 'clang-tidy': Segmentation fault

@SunBlack do you have any idea how to solve this?

Start with the minimal CMakeLists.txt and main.cpp reproduction, especially the inclusion of pcl/visualization/pcl_visualizer.h and the CMAKE_CXX_CLANG_TIDY=clang-tidy configuration. Run the reported cmake and make commands on Ubuntu 18.04 to confirm the failure; done means clang-tidy no longer segfaults for this example.
