            Bug ID: 19249
           Summary: lambda crash (hard to explain without source)
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

#include <functional>

int ttt(std::function<void()> const &f) {
    return 0;

int main() {
    auto x = ttt([&x] {});
    return 0;

The most important that you will try to catch to closure *auto* variable
returned from function where you pass lambda.

So this code compiling without problem:

int main() {
    int x = ttt([&x] {});
    return 0;
