No, the problem is that you are not speaking of the same thing.

$ grep -c pthread libavfilter/*vmaf*

-> our code depends on pthreads for this filters, it must be expressed
in configure: Carl Eugen's patch is right, there is no need to bugreport
anything. His explanations later were wrong, but it may only be caused
by the confusion you brought.

What you describe is possibly true, but not related.
