Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2014-09-19 Ever confirmed|0 |1 --- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> --- In mainline we don't ICE anymore. This is enough to reproduce the issue: struct Iterator { int& operator*(); }; void foo(Iterator begin) { auto x = [](const decltype(*begin)) { }; } Note, anyway, that the EDG front-end warns.
