I tried the program on the machine I have at school (supplied by the school for
my Masters work) and here, instead of swapping ad infinitum, the program
segfaults. Here's what gdb tells me :
[...]
[0002503/000] DBG: Waverider::setupSky() called.

So it seems that my call to setBackground() eventually leads to a segfault. But
as far as I can see, the background creation code is almost identical to the
one in the example (only the image loading changes). Any idea what could cause
this?
I'll look into why it causes a segfault here and not at home later tonight. I
suspect I have some mixed lib versions on my home machine... Which may explain
the problem with shaders in the other thread too.
Thanks,
J-S
