[gnugo-devel] valgrind ticket 124

[alain Baeckeroot]

Hi

One bug may hide an other bug.
There are some mysterious failures with the twin patch, even when it is not 
used.
I'm still tracking this, and suspect a bug somewhere.

With the additional assertion made by gunnar 5/7 of the mysterious failures
stepped on the bug (with standard gnugo 3.7.9 + assertion)
So it seems this bug hits very often, even if valgrind complained only once.

Alain
