Package: libstdc++6-4.4-dev
Version: 4.4.4-7
Severity: normal
File: /usr/include/c++/4.4/tuple
Forwarded: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45228
The following program fails to compile:
======================================================================
#include <tuple>
typedef std::tuple<int,int,int> Tuple;
//typedef std::tuple<int,int> Tuple;
Tuple A() { return Tuple(); }
const Tuple B() { return Tuple(); }
int main()
{
Tuple test(B());
//Tuple test(A());
}
======================================================================
The program compiles successfully when A() is used instead of B() to
initialize the "test", or when a two-element tuple is used instead of a
three-element tuple.
In addition to the compiler above, this has also happened with gcc-snapshot
20100702-1.
The compiler output is
======================================================================
