That looks like a bug in the post processing cleanup to me. The context the
shaders belong to is destroyed before pp_free is called to destroy the shaders
created from that context.

Since the bisected patch explicitly destroys all bound shaders of a context if
the context is destroyed we get a double free of the shader.
