Preprocessed source to reproduce the problem

When I run the command:
$ /usr/bin/c++   -DWITH_VERBOSE_COLLIDER -DWITH_VERBOSE_OBS_MANAGER -std=c++11 -Wall -Wextra -pedantic -Wconversion -g -std=c++11 -Wall -Wextra -pedantic -Wconversion -isystem /home/michele/dev/code/cpp/clooneljump/lib/tree-2.81/src -I/home/michele/dev/code/cpp/clooneljump/src -I/home/michele/dev/code/cpp/clooneljump/src/movers -I/home/michele/dev/code/cpp/clooneljump/include -I. -I/home/michele/dev/code/cpp/clooneljump/lib/physfs-2.0.3 -MMD -MT CMakeFiles/CloonelJump.dir/src/horzcollisionbar.cpp.o -MF "CMakeFiles/CloonelJump.dir/src/horzcollisionbar.cpp.o.d" -o CMakeFiles/CloonelJump.dir/src/horzcollisionbar.cpp.o -c /home/michele/dev/code/cpp/clooneljump/src/horzcollisionbar.cpp

I get this error:
/home/michele/dev/code/cpp/clooneljump/src/horzcollisionbar.cpp: In function ‘std::pair<bool, cloonel::Line<float, 2u> > cloonel::{anonymous}::getOverlap(float, const Line2D&, const Line2D&, const float2&, const float2&)’:

                                         ^
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.gentoo.org/> for instructions.

Line2D is a typedef for Line<float, 2>. I rebuilt the code with clang 3.3 and had no problems with it.
I'm attaching the preprocessed file, but I'm available to put the full source code somewhere (it's from an open source project, but the part I'm working on has not been committed yet).

I've pushed it, you can find the full code here: https://bitbucket.org/King_DuckZ/clooneljump/commits/tag/gcc_49_error

this appears to be fixed w/gcc-4.9.1
