I''m writing a program that started off as C and swiched to C++, I have a struct that has vector members I malloc the struct, but sometimes I''m getting a seg fault when I try to push_back(item) on the vector. I can change the other variables in the struct and chage. The problem happens when I am dealing withe a pointer to the stuct (called line): line->members.push_back(item); and not necessaritly the first push. Shouldn''t I be able to push on an arbitary number of items? I appreciate any help I was up to 11 in the morning last night and It''s 6:40am here again, and this was due two days ago! Thanks Nick

Never use malloc() in C++. The vector constructor isn't being called. use new instead.

Oh, and of course, never use free() either. Use delete or delete[] instead.

Thanks
It''s weird though, it''s not the first push that fails, I''ll try that though.

Well, if you''re implementng operator new() and/or operator delete() [admittedly pretty advanced stuff...], then you''ll
need to fall back to malloc/free to avoid infinite recursion.

Very true... tho given that he didn''t even know to use new, I''m guessing it''ll be a little while before he has need for overloading new or delete.
