c++ - New and delete operators without effect on the contents of a Deque of pointers to this class -

i have problem have been tackling since last 2 days, rather inexperienced programmer normal assume. question may have easy solution, couldn't find quick reference, decided ask others.

in 1 thread of application, create new, pointer user defined class. after it, push new created pointer deque of pointers user defined class, push_back() method.

this deque under concern had been passed thread main function of application, contents of user-defined class processed in main loop. thus, when new pointer enters deque, taken in main thread, , used.

my problem need make sure memory allocated contents of class should deallocated after use, because store large image arrays. otherwise, program crashes. this, have used delete after push_back() call in thread, assuming memory free, stored in deque. however, apparently, contents of address pointed pointer in deque deleted. not desire.

is there way decouple both, maybe without introducing pointers? think new , delete valid in pointers. more precisely, there way pass contents of class deque , delete it, without affecting in deque?

instead of using raw pointers, consider using boost pointer container library:

boost.pointer container provides containers holding heap-allocated objects in exception-safe manner , minimal overhead. aim of library in particular make oo programming easier in c++ establishing standard set of classes, methods , designs dealing oo specific problems

but valid choice if:

the stored objects not shared, owned exclusively, or  overhead implied smart pointers inappropriate 

otherwise, if image file pointers shared, consider using std::shared_ptr pointed out in comments.

if boost pointer container fits needs, can use boost::ptr_deque
