Bug #: 13015
Summary: C++11 code that calls a function with struct literal
with function call in it makes clang 3.1 segfault
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW

Compile the attached clang_bug.cpp code with Clang 3.1:
$ cat clang_bug.cpp
#include <functional>
#include <list>
typedef std::function<float (float)> Func;
struct Record { Func func; int a; };
static int foo() {
return 1;
}
static void bar(Record record) {}
void add_func(Func func) {
bar({func, foo()});
}
$ clang -v
clang version 3.1 (branches/release_31)
Target: x86_64-unknown-linux-gnu
Thread model: posix
