Problems with Data Types, High Severity (2)

tracker_manager.hpp
namespace libtorrent
[+] class tracker_connection (1)

	Change	Effect
1	Size of this class has been increased from 232 bytes to 240 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed..

[+] affected symbols (7)

tracker_connection::close ( )

This method is from 'tracker_connection' class.

tracker_connection::fail ( int code, char const* msg )

This method is from 'tracker_connection' class.

tracker_connection::fail_timeout ( )

This method is from 'tracker_connection' class.

tracker_connection::requester ( )

This method is from 'tracker_connection' class.

tracker_connection::tracker_connection [in-charge] ( tracker_manager& man, tracker_request const& req, io_service& ios, address bind_interface, boost::weak_ptr<request_callback> r )

This constructor is from 'tracker_connection' class.

tracker_connection::~tracker_connection [in-charge] ( )

This method is from 'tracker_connection' class.

tracker_manager::remove_request ( tracker_connection const* p1 )

1st parameter 'p1' (pointer) has base type 'tracker_connection'.

[+] class tracker_request (1)

	Change	Effect
1	Size of this class has been changed from 96 bytes to 104 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.
