OpenGL command crashing under Lazarus but not Dephi 5

[cragwolf]

When you say you tested it using the latest FPC compiler, does that include the one under Lazarus 0.9.18?

I don't know what Lazarus 0.9.18 uses, because I don't use Lazarus.

(I used just the glunprojecttest.dpr and sdlapplicationunit.pas files)

EDIT: wait a minute, does this mean you used the GLU and GL files that come with FPC and not the ones that I supplied?

I tested your demo with the GL and GLU files that come with FPCv2.0.4, and I tested it with the GL and GLU files that come with JEDI-SDLv1.0 (beta). Your GL and GLU units seem to come from JEDI-SDL, although I'm not sure which version of JEDI-SDL.
