The crash comes during estimate_territorial_value during
the evaluation of B:F13. The move has been tried and W:E13
is removed from the board. But E13 is marked in the saved_stones
array which is then passed to matchpat as a goal.
As I noted in my previous message this must be different
from the problem in global:4.
Here's the backtrace:
