I''ve created and tested a doubly linked list. Now I want to call that list from in a class like class something{ private: list *l; public: something(){l = new list();} dosomething(){ /*initialize data*/ l.push(data); } } int main(){ something s; s.printdata(); } However when I try this I''m looping through pushing mutliple nodes in a row my program seg faults in the dosomething function on the section iteration of my loop. Also when I inspect the issue futher the previous pointer has been moved from a valid memmory address to 0x18. Any help on how to declare this list within a class would be helpful. Thank you, Paul

As I''ve stated above I''ve tested the list and it works correctly for add, iterate and delete my issue is when declaring the list as a member of another class then running it. And the issue occurs before I eliminate a node in the list. It appears to be a memory referencing error in the class definition because it works if I declare the list in the main file and pass it into the class, such as:

void main(){
list *l = new list();
something *s = new something(l);
dosomething();
printlist();
}

and sorry no I can''t post the header it''s part of a project I have yet to release to the open source community and the head of the project doesn''t want the source out there yet.

PS sorry this isn''t quite a beginner question but I thought someone might have run into the problem before.

thanks,
Paul
