The code below does not compile with g++ 3.0, but it seems correct
judging by my C++ books.
Wichert.
#include <memory>
#include <list>
using namespace std;
int main(int, char**) {
auto_ptr<int> api(new int(5));
list<auto_ptr<int> > lapi;
lapi.push_back(api);
return 0;
}
[Comment by Laurent Bonnaud <[EMAIL PROTECTED]>:]
This one is much more complicated. I agree with Wichert that this
should work, but this is much more involved. I could not think about
an easy fix.
If you look at /usr/include/g++-v3/bits/std_memory.h, you'll see this
comment that lacks precision:
// According to the C++ standard, these conversions are required. Most
// present-day compilers, however, do not enforce that requirement---and,
// in fact, most present-day compilers do not support the language
// features that these conversions rely on.
The methods it refers too are crucial in making this testcase work. So
the real question is: does g++ 3.0 support the necessary language
features ?
