--- Comment #6 from Night Nord NightNord@gmail.com 2011-03-12 07:33:32 CST --- Ahh, I'm terribly sorry, I've mistaken with TRACE macro, so it was giving me gl_info pointer as context's one making me confused.
Right you are, this call comes just from context_destroy_fbo and commenting it out removes this crash. I'm sorry for my confusion and assuming this is wine bug.
Well, ati.cchtml.com bugzilla seems to be flushed and report from bug 21540 is lost, so, I guess, I should fill another one.
