#6167: Assignment from a temporary of a class containing boost::unordered_map
members fails with GNU GCC.
---------------------------------------------+------------------------------
Reporter: Geurt Vos <geurt.vos@â¦> | Owner: danieljames
Type: Bugs | Status: new
Milestone: To Be Determined | Component: unordered
Version: Boost 1.48.0 | Severity: Problem
Keywords: |
---------------------------------------------+------------------------------
With boost 1.48.0 the following code does not compile anymore:
----
#include <boost/unordered_map.hpp>
struct A {
boost::unordered_map<int, int> m;
};
void Test()
{
A a;[[BR]]
a = A();
}
----
GCC 4.6.1 & GCC 4.1.2 say:
11:8: error: no match for âoperator=â in âa = A()â[[BR]]
11:8: note: candidate is:[[BR]]
4:8: note: A& A::operator=(A&)[[BR]]
4:8: note: no known conversion for argument 1 from âAâ to âA&â[[BR]]
When GCC 4.6.1 is set as C++11 compiler (-std=c++0x), it compiles without
errors.
