Commit 64afe6e9eb4841f35317da4393de21a047a883b3 upstream.
The current pending table parsing code assumes that we keep the previous read of the pending bits, but keep that variable in the current block, making sure it is discarded on each loop.
We end-up using whatever is on the stack. Who knows, it might just be the right thing...
