Re: serious problem with set<string>::iterator usage

The problem is an invalid iterator. When I'm using a
set<string>::iterator in side the main funcion I don't see the
problme. when I use it in a class function it always turns up
invalid. I tried it with set<int> and had no problem. This seems
to be related to using a more complex data type but for some reason
only in a class.
Below is a short example that demonstrates the problem I'm having. I've
tried this in VC++6 and VC++8 and GNUC++ 3.4.4 with the same
results.
I sure hope there is something I'm missing here.

#include <set>
#include <string>
#include <iostream>
using namespace std;

class COptions
{
public:
void SetTest(void)
{
 string tmpstr;
 set <string> strset;
 set <string>::iterator sPOS;

 strset.insert("2:This");
 strset.insert("2:is");
 strset.insert("2:a");
 strset.insert("2:test");

 for(sPOS = strset.begin(); sPOS != strset.end(); sPOS++);
