Re: [gnugo-devel] paul_3_13.8 and paul_3_13.9

[bump]

I had been doing a similar experiment using a slightly different
patch but identical in purpose.

Although it produces a crash in global:1 it does NOT crash
in global:4, where we have have a changed result, so I think
there may be two different bugs.

Maybe we should take this discussion of why paul_3_13.8a has
a regression delta to the list.
