[Bug c++/41480] New: std::map.erase on cygwin

[lifelong830114 at gmail dot com]

The program goto endless loops when run erase() in a for loop,as fallows:

#include <map>
#include <stdio.h>
std::map<int , int> mymap;
int main() {
 mymap[2] =3 ;
 mymap[1] = 4;
 printf("**********test map.erase*********\n");
 std::map<int,int>::iterator it;
 it = mymap.begin(); 
 for (; it != mymap.end() ; it++)  {
   mymap.erase((*it).first);
 }
 return 0; 
}

I have try to delete the line "printf("**********test
map.erase*********\n");",then it worked correctly!

The configure string is :
./configure --prefix=/usr/local/gcc-4.2.0 --program-suffix=-420
--enable-language=c,c++
