This GL 3.3 context is a 'core' profile context.

This is a non-core (legacy) context. (We only support GL 3.0 for
non-core contexts.)

See GLX_CONTEXT_CORE_PROFILE_BIT_ARB on:
http://www.opengl.org/registry/specs/ARB/glx_create_context.txt

Or, perhaps the glxinfo source:
http://cgit.freedesktop.org/mesa/demos/plain/src/xdemos/glxinfo.c

What are you using to create the GL context? (SDL?)
