gcc-4.9.0 build log

Trying to build geant4.10.02.p01 on 
Arch:
RH Enterprise 6.5
Kernel:  2.6.32-431.20.3.el6.x86_64 

Here's my cmake:
 
cmake  --trace-expand --debug-output -D CMAKE_BUILD_TYPE=Release \
       -DGEANT4_BUILD_MULTITHREADED=ON \
       -DGEANT4_USE_RAYTRACER_X11=ON \
       -DGEANT4_USE_OPENGL_X11=ON \
       -DGEANT4_INSTALL_DATA=ON \
       -DGEANT4_USE_QT=ON \
       -DGEANT4_INSTALL_DATADIR=/usr/local/pacerepov1/${SOFTWARE}/${VERSION}/data \
       -DCMAKE_INSTALL_PREFIX
           =/usr/local/pacerepov1/${SOFTWARE}/${VERSION}/${COMPILERVERSION} \
       -DGEANT4_INSTALL_DATA_TIMEOUT=6000   \
   ../ \
    && make -j8 \
    && make install
 
 * both ON/OFF switches for each option has been tried/tested.
 * it works if you turn off multithread (the build is available/usable)
 
Here are the compilers I tried building it with 
   intel-15.0
   intel-14.0.2
   gcc-4.9.0
   gcc-4.7.2
   gcc-4.4.5/4.4.7
 
Other modules loaded
   cmake/3.5.2
   qt/5.5.1
 
Below is the compile error message  GCC-4.9.0
