Michael McCandless commented on LUCENE-3897:
--------------------------------------------
I think the problem is when we force a backtrace (if it's >= 1024 chars since
the last backtrace)... I think we are not correctly pruning all paths in this
case.
Unlike the natural backtrace, which happens whenever there is only 1 path (ie
the parsing is unambiguous from that point backwards), the forced backtrace may
have more than one live path.
Have to mull how to fix...
