Interesting....

I added the following to the autogenerated CMakeLists.txt file

# Created by the script cgal_create_cmake_script
# This is the CMake script for compiling a CGAL application.


project( meshing-work_test )

CMAKE_MINIMUM_REQUIRED(VERSION 2.4.5)
# ADDED FOR DEBUG
set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true)

I recompiled and the code worked. So I suspect that it is the compiler bug. Thanks for the help.

It's probable that you are a victim of the gcc bug mentioned in the FAQ.
Try to use a more recent compiler, or remove optimization (tell cmake
to use the debug mode instead of the default which is the release).

       On execution the example fails at the line (47):

   Describe "fails", please.


   Also, which compiler version are you using ?
   I'm thinking it can be related to
