Thanks for your bug report. Please do have a look at

http://www.gnu.org/software/gcc/bugs.html

I could not really reproduce the problem, because I don't have
GL/glut.h.

In any case, your error is in

int numchild = 3;

typedef struct treenode
{
  struct treenode * next;
  struct treenode * child[numchild];

You can't have a class with a variable-size member.

Regards,
Martin
