I'm trying to run the cube example on linux, I built the libglfw3.a from the zip source file and placed it where dub expects it.

Upon running (compiled with DMD) it segfaults and investigation with GDB shows:

Starting program: /home/webfreak/dev/teraflop-d/bin/teraflop_cube

I've made some changes to help address this issue in #26. However, I cannot reproduce the specific segfault you cited in MeshBase.

@WebFreak001 What happens if you run:

  1. git clone --single-branch --branch "issue/13-segfault" https://github.com/chances/teraflop-d.git
  2. cd teraflop-d
  3. dub run teraflop:cube
