[gnugo-devel] Crash again

[Portela Fernand]

Hi,

While doing some owl-tuning, I got this somewhere in nngs3.tst (around 840)
:

***assertion failure:
reading.c:397 - !((acode != 0) && (dcode == 5 && dpos == 0)) near PASS***

The following patch solves the problem, but I haven't tried to figure out if
it makes sense or not (to me, it seems strange that more than one attack on
a
string could be stored in the persistent cache). Possibly, the problem is
somewhere else and/or "deeper" and this patch could be a bad solution.

/nando
