I rebuilt fluxus with the above alteration...no change I'm afraid.
The following line (not shown above) is a call to DrawText() - I
commented out this line, rebuilt and the crash did not occur. Of
course no fps was displayed either, but perhaps the problem is in that
function.

I had a poke around, uncommented to call to DrawText and commented out
the following on line 677:
    glutBitmapCharacter(GLUT_BITMAP_HELVETICA_12, Text.c_str()[n]);

Again, no crash. Maybe glut is the culprit.

I may have noticed some glut warnings during the scons build. I will
try to get the stdout into a text file to have a look through.
