Sourcecode: gcc-2.96 version File versions


This is a C++ program that, by my
understanding, should compile cleanly but does not.  I don't have
another compiler to test it with, unfortnately (eg. the Sun compiler).
I'd try it on gcc-2.95 but I can't risk installing a non-stable
version of g++ at this time.  Hopefully you can try it.

#include <multiset.h>

int main(void)
  multiset<int, less<int> > x;
  multiset<int, less<int> >::iterator iter = x.begin();
  int& y __attribute__((unused)) = *iter;
[patricia:~]g++ test.cpp
test.cpp: In function `int main(...)':
test.cpp:8: warning: conversion from `const int' to `int &' discards const
