I think I know what's going on. In any case the test case complexity
can be radically reduced by replacing all "genmove white" with "play
white pass".

It's a safe bet that the move history collapsing around line 1000 is
the triggering factor. I have a feeling that the bug may have been
introduced with the patch arend_3_13.1.
