Crash on Native Linux program

I've been trying to run a HDR demo that I have downloaded from:

http://www.humus.name/index.php?page=3D&ID=62

There's a Windows and Linux version of the demo and both (the one for Windows running under Wine) are crashing when I try to run them.

This is on Ubuntu 10.10 + Drivers and Kernel from Xorg-edgers, GM45 video card:
Linux rave-dell 2.6.37-9-generic-pae #22-Ubuntu SMP Fri Dec 10 16:46:16 UTC 2010 i686 GNU/Linux

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)

I'm attaching both backtraces. The source code of the demo is available in the link I gave you before.

For your information, this fix will also fix one segmentation fault with OpenGL ES 2.0 conformance test suite
