This one has been around at least as far back as 3.0.1 (which is the first copy of POI we have in our own vendor tree.)

For some reason a lot of documents still work even though this bug exists, so the offset must be 0 fairly often.  Even so, this causes some nasty random errors.

I added a unit test which exhibits the issue.  My own complete testing will follow.

Proposed patch

Confirming that this works on our existing test data, in addition to fixing three files encountered so far.
