As per code, it is difficult to predict why the brick was crashed in this function but I think we can avoid this crash after saving the host_name/base_path in the starting of this function(posix_fs_health_check). Though we do cancel this health check thread at the time of calling posix_fini and call this function(posix_fs_health_check) between cancellation point so ideally hostname and base_path will be free after calling this function (posix_fs_health_check) but here it seems hostname/base_path are freed at the time of calling gf_event.
