title: Segmentation fault in fgets
body: <p>After debugging my code I get the following error:</p>
  
  <blockquote>
    <p>Program received signal SIGSEGV, Segmentation fault.
    0xb7d79a67 in fgets () from /lib/i386-linux-gnu/libc.so.6</p>
  </blockquote>
  
  <p>Can anybody explain to me what this means? It's a project built using CMake and OpenGL.</p>
