How to get the first element of a std::set

Question

I you all,

I found a strange bug in my software.

Inside a while loop where I remove elements from a std::set, I want always to take the first element until the container is empty:

std::set< int*> nodes;
// Fill nodes 
for (int i=0; i<10;i++)
   nodes.insert(new int);
//
while (!nodes.empty())
{
int* pivot  = (*nodes.begin());
// do some operation with pivot erasing some elements from nodes
}

I found that implementing the first element this way works with gcc but not with MSVC, it crashes where I try to dereference the (*nodes.begin()) iterator.

Do the two implementation of std::set behave differently?

I would like to have a data structure with no differences of implementation, is it possible?

Probably I must change data structure for this kind of operations

Solution

your code work well in VS2010, mybe you should update your vcc.
