I’m encountering a segmentation fault in the all_neighbors_have_labels function within my projcet. The code snippet causing the issue is:

return board.inner_board[start_x][start_y]->role != none && board.inner_board[start_x + 1][start_y]->role != none &&
       // ... (similar checks for other neighbors)

From here in all_neighbors_have_labels

Strangely, I can access individual elements of the board.inner_board array in separate lines before the return statement, like so:

board.inner_board[start_x];
board.inner_board[start_x][start_y];
board.inner_board[start_x][start_y]->role;

Again defined here in all_neighbors_have_labels

These individual accesses seem to work, but when combined in the return statement, a segmentation fault occurs even when only accessing board.inner_board[start_x][start_y] , as opposed to start_x +/- 1 or start_y +/- 1

Note: board.inner_board array is initialized in the _create_labeled_board function, which is called from generate_board_from_config in board.c.

Despite individual element accesses seeming successful, the function crashes in the return statement. What could be causing this segmentation fault, and how can I fix it?
