From: "3dw4rd at verizon dot net" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/49598] New: Ice on lambda with implicit capture by value. Date: Thu, 30 Jun 2011 20:31:00 -0000 [thread overview] Message-ID: <bug-49598-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49598 Summary: Ice on lambda with implicit capture by value. Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned@gcc.gnu.org ReportedBy: 3dw4rd@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 int int & D.28407.__ir = ir; lamb2.cpp:10:1: internal compiler error: verify_gimple failed Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. -----------------------------------------------
