Pushed your fix to master and 9.5, with two very minor changes:
1) I moved the BufferDescriptorGetBuffer() call in PinBuffer_Locked() to  after the spinlock release. It's rather
minor,but there seems  little reason to do it before except the assert, which isn't compiled  in production.
 
2) I removed the two asserts you added. They essentially asserted that  i + 1 == i + 1.

Thanks again for the catch and patch.
