Qt Creator freezes and CPU usage is 100% after a project is being opened in Ubuntu 16.04. To reproduce the bug

1. sudo apt-get install libxml2-dev libraw1394-dev libncurses5-dev swig libopenigtlink-dev flite cmake-curses-gui libopencv-dev git subversion gfortran libcppunit-dev fluid
2. git clone --recursive https://github.com/jhu-cisst/cisst-saw.git
3. open project by opening CMakeLists.txt via Qt Creator (I am using CMAKE 3.9.4)
4. make sure ClangRefactoring plugin is loaded
5. configure the project
6. build the project and then wait for build fail
7. turn on CISST_HAS_CISSTNETLIB in CMake (see build-pro1.png) and then Apply Configuration Changes
8. open CMakeCache.txt which is inside the build folder (see build-pro1.png)
9. change CISSTNETLIB_DOWNLOAD_NOW:BOOL=OFF to CISSTNETLIB_DOWNLOAD_NOW:BOOL=ON (see build-pro1.png) and then Run CMake inside Qt Creator by right clicking project and then clicking Run CMake on pop up menu
10. press yes button to reload CMakeCache.txt and then change CISSTNETLIB_DOWNLOAD_ARCHITECTURE:STRING=undefined to CISSTNETLIB_DOWNLOAD_ARCHITECTURE:STRING="x86_64" (see build-pro2.png) and then Run CMake inside Qt Creator 
11. build the project and then wait for build fail
12. open cisst-saw\cisst\cisstVector\vctDynamicVector.h in Qt Creator
13. open system monitor, you can see CPU usage jump 100% and then Qt Creator will freeze
