warning: Hit heuristic-fence-post without finding enclosing function for address 0x200002d0020
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.
Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
