Thanks for the test. When Ken pointed out the source of the problem I was sure
I'd already done work to fix this as all the data used to be attached to
gl_linked_shader which gets trashed every time we relink. I moved the data
required by the backend to gl_shader_program_data but it seems I forgot to
finish of the last step of creating a fresh instance of gl_shader_program_data
when we link. I've sent some patches to fix this:
