Qt Creator crashes when tries to open a CMake-base project in which has WX_PRECOMP definition. CMake stage seems is passed without any problem. Crash happens on Parsing C/C++ files. To reproduce this download latest wxWidgets sources https://github.com/wxWidgets/wxWidgets/releases/download/v3.0.4/wxWidgets-3.0.4.zip, unpack and put attached CMakeLists.txt to wxWidgets-3.0.4 folder. Then try to open and build CMakeLists.txt in Creator.

CMakeLists.txt:

cmake_minimum_required(VERSION 3.3)
project(wxWidgets)
include_directories(include)
add_definitions(-DWX_PRECOMP)
set(SOURCES src/common/any.cpp)
add_library(${PROJECT_NAME} SHARED ${SOURCES})
