I can reproduce the problem. I'll have a look at it.
from ttcr.
Due to the velocity contrast, the ray path was getting pretty close to the limite of the grid, and due to approximations when computing the travel time gradient, the ray direction was pointing slightly outside the grid. This is a limitation of the approach based on computing ray paths from travel times. I updated the example by moving the source & receiver that were close to the limit, and it now runs fine.
So, in general, when you get this problem, you can either extend a bit the grid, or move the src/rcv away from the grid limits.
