hi everybody,

I'm using the list template as a channel between a master and a slave. I use "push_back()" to insert a message into the list and "pop_front()" from the front the list in each cycle. But maybe since my message is too long (sizeof(message)=220), although the program is compilable, it can only run to the second cycle and pop out the debug error:

HEAP CORRUPTION DETECTED: after Normal block(#182) at 0x00389730. CRT detected that the application wrote to memory after end of heap butter.

If I delete the "pop_front()" function, the program can run to the end of the program.

Could somebody please tell me how to extend the memory for this list? or how to solve this problem.

Thank a lot.

I dont think the list is the correct container to use.
The function 'list.pop_front()' removes the first element but does not return it.
The list is a double linked list so you can insert and remove elements easily which you dont seem to need.
A vector should do the job which you can use like an array. Not tested but try something like:

std::vector<string> myString;
myString.reserve(NUMBER_OF_STRINGS);
myString[1] = "Hello";
cout << myString[1];
