geometry shaders don't work

    Hi there,
    on the last MBP, with an AMD Radeon HD 6750M, geometry shaders from cycling simply don't work.
    Lots of errors "invalid operation" type, I really can't figure out where it comes from.
    Could be very very extremely nice if someone had an idea of what happens with those geometry shaders, I've not found any related post.
