After I added the implementation of the BillboardRender constructor,
g++ crashes while compiling.

Command line:
/opt/nspire/Ndless/ndless-sdk/toolchain/install/bin/arm-none-eabi-g++
-mcpu=arm926ej-s -I /home/fabian/.ndless/include -I

-marm -ffast-math -mcpu=arm926ej-s -fno-math-errno -fno-tree-vectorize
-fomit-frame-pointer -flto -c billboardrenderer.cpp -o billboardrenderer.o

gcc version 4.9.0 (GCC)

Constructor:
BillboardRenderer::BillboardRenderer(std::map<uint8_t, std::tuple<unsigned int,
unsigned int, const char*>> map) : map(map)
{
}

I attached the files it generates with -save-temps.
