warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0xfffffe00013a6174
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable). In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.
