Summary: Ice on lambda with implicit capture by value.
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: 3dw...@verizon.net
I have a brand new (r175707) 4.7 build on x86_64 GNU/Linux.
I saw an error with lambdas on stackoverflow:
-----------------------------------------------
#include <iostream>
using std::cout;
using std::endl;
int
main()
{
int i = 10;
int& ir = i;
[=] // [i, ir] explicit capture works.
{
cout << "value capture" << endl
<< "i: " << i << endl
<< "ir: " << ir << endl
<< "&i: " << &i << endl
<< "&ir: " << &ir << endl
<< endl;
}();
}
-----------------------------------------------
This is reduced somewhat.
I get:
-----------------------------------------------
[ed@localhost ~]$ ./bin/bin/g++ -std=c++0x -o lamb2 lamb2.cpp
lamb2.cpp: In function ‘int main()’:
lamb2.cpp:10:1: error: non-trivial conversion at assignment

D.28407.__ir = ir;
