[ace-users] segmentation fault on exit from main()

[Johnny Willemsen]

Hi,
 
Thanks for using the PRF form. Probably you have registered an eventhandler
that is already destructed, try to use valgrind to get more information
about the type of event handler.

	    ACE VERSION: 5.5.7 and 5.4.7 (ubuntu package)

	 

	    HOST MACHINE and OPERATING SYSTEM:

	            I486-linux-gnu; linux Ubuntu 6.06

	 

	    COMPILER NAME AND VERSION (AND PATCHLEVEL):

	            Gcc version 4.0.3 (Ubuntu 4.0.3-lubuntu5)

	 

	    AREA/CLASS/EXAMPLE AFFECTED:

	 

	template <class ACE_SELECT_REACTOR_TOKEN> int

	            ACE_Select_Reactor_T<ACE_SELECT_REACTOR_TOKEN>::close
(void)

	{

	            ACE_TRACE ("ACE_Select_Reactor_T::close");

	            ACE_MT (ACE_GUARD_RETURN (ACE_SELECT_REACTOR_TOKEN,
ace_mon, this->token_, -1));

	            

	            if (this->delete_signal_handler_)

	            {

	                        delete this->signal_handler_;

	                        this->signal_handler_ = 0;

	                        this->delete_signal_handler_ = 0;

	            }

	            

	            this->handler_rep_.close ();  <ç========== debug reports
this line

	            

	            if (this->delete_timer_queue_)

	            {

	                        delete this->timer_queue_;

	 

	    DOES THE PROBLEM AFFECT:

	        EXECUTION:

	            Exit from main()

	 

	    SYNOPSIS:

	            Get a segmentation Fault when exiting main(), when
running on Linux

	 

	    DESCRIPTION:

	            After execution of the program, when the Reactor event
handler loop exits, the main exits at the statement “return 0;”.

	            Then I receive the message that a segmentation fault
where detected.

	            

	            It is only on Linux. I don’t get any error messages
running on windows (this is of cause another Reactor implementation).

	 

	            (It is the same code as I posted 19/09 “checking
application for memory leaks”)

	 

	Best regards
