Thanks. This does produce a crash. It is a somewhat artificial situation since you are asking to confirm the safety of a move at P2 but P2 is already occupied. So this is not a crash that should happen as a result of normal move generation. The abort is at line 418 of combination.c. My opinion is that this should be fixed in the unstable line, but it doesn't need to be fixed for GNU Go 3.8. Not because it isn't worth fixing - just because it is conservative to minimize changes to the engine just before a stable release. Backtrace below.
