Hey everyone,

First to get the usual details out of the way:

Late 2008 Macbook Pro
OSX Lion 10.7.3
2.53 GHz Intel Core 2 Duo
NVIDIA GeForce 9400M GT 512 MB

I have been working on a graphics project (game) with 5 others. Each of them can run it, including one person who is also using XCode 4.

We are using OpenGL, and SDL to make it.

We just recently demo'ed our progress on my laptop and everything went great.

I have made no changes, not a single character, to the code and now it is segfaulting on a glCreateShader call. It is passed GL_VERTEX_SHADER.

It seems to me that OpenGL has just crapped out all of a sudden and I have no idea why.

I ran it by the nearest Apple Store and they ran the usual hardware diagnostics and didn't find anything they weren't expecting.

I have tried running the code both from XCode 4 and the terminal, both compile successfully and both segfault in the same place.

I think I just recently updated to 10.7.3, so there could be an issue there. I have no idea how to roll back the update, or if it's even possible. (Doesn't seem to be from my quick googling.)

Any thoughts?

Thank you,
Tag Ashby
