Please CC 101371-quiet@bugs.debian.org on replies. Log of report can be found at http://bugs.debian.org/101371 ] 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 <Laurent.Bonnaud@inpg.fr>:] 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 ? >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
