crash at vector::push_back.

[Jijo Raj]

Can be due to a lot of reasons. Could you please provide relevant code snippet and call stack during crash? Regards, Jijo.

Why are you mixing MFC collections with STL ones?

Is it a serious issue(mixing MFC with STL)? please explain.

Looks like a CRT invalid argument error. You can use _set_invalid_parameter_handler[^] to set a custom handler for whatever invalid argument is being passed. Note that not correctly handling the error could mask the real problem. Best Wishes, -David Delaune

It's not FATAL - but the two mindsets of the framework designers are quite different. So you're setting yourself up for confusion. Which is never good. I find it confusing enough just getting out of bed. Iain.

Nope, if you're able to master both. Anyway, if you're able to master both then you don't mix them. :)

Also the quality of the two mindsets is quite different (as usual this is going on my arrogant...) :-D

The problem is still not solved. I have some classes that inherit from vectors. I have a vector of POSITION(in afx.h)

// abstract iteration position
struct __POSITION {};
typedef __POSITION* POSITION;

So when I try to push a POSITION value to the vector I get this crash saying invalid parameter. In call stack I see its trying to push(insert) a value of different type (ref. classes that inherit from vectors) other than POSITION. How is this possible? Please help!!!

I had the same problem when porting from VS2005 to VS2008. I avoided it using dynamic allocation something like this: std::vector<???> *v; v = new ???; v->push_back(***) This works in both debug and release mode :)
