%%%Blender crashes with a Segfault when the following setup is created, please follow the steps to retrace:

Machine: Linux 64 bit - Slackware 13.37
8 GB ram
Processor: Q6600 - Quad
Blender version: Latest SVN compiled with Make

Retrace:

Open a new clean default scene.
Throw a texture (any IMAGE texture / .jpg file) on the Default CUBE.
Map it!
Activate NORMAL mapping (Tick NORMAL and set a value, any + value)
Open the Tool menu with N and go to DISPLAY, set Shading to GLSL
Now...set the VIEWPORT shading to TEXTURED
Go to your TEXTURE menu again and scroll down until you find the Bump Mapping menu. Set the dropdown menu to BEST QUALITY or DEFAULT
Crashes with the following error messages:

%%%I can confirm this issue on Linux 64, Ubuntu 11.04, 8GB RAM, Intel Core Duo 2.33 processor. Blender doesn't crash, but it freezes up, and stops responding. %%%

%%%I can confirm this with recent svn (40118). Order doesn't matter. As soon as you click on "best quality" blender instantly crashes.
The "GPU invalid function" messages don't seem do relate to this. They appear as soon as you switch from multitexture to GLSL. No matter if NOR is enabled or not.

It is also not related to best quality. Crash happens if you switch to any other method and then back to "default". Other modes seem to work fine.

Here is the backtrace of GDB:

%%%I did some further testing. the bug exists since svn revision 40061 by Benoit Bolsee, which introduces the python module to export GLSL shader.
So he might look into this.%%%
