title="NEW - crash on invalid c++ code with "-std=c++14" on x86_64-linux-gnu (UNREACHABLE executed at /path/to/StmtProfile.cpp:1017!)"
href="show_bug.cgi?id=28793">bug 28793</a>.
However, this bug can also be reproduced with -std=c++11.
I am using:
clang version 5.0.0 (trunk 304555)
Target: x86_64-unknown-linux-gnu

Here is the reproducible:
// ============================================================================
template <typename _Ty> struct add_rvalue_reference {
typedef _Ty &&type;
};
template <typename _Ty> typename add_rvalue_reference<_Ty>::type declval();
template <typename _Fty> struct _Result_of {
static auto _Fn() -> decltype(declval<_Fty>()());
};
template <typename T> struct Future {};
template <typename Function>
Future<typename _Result_of<Function>::type> Firstly(Function) {
}
void Join() {
Firstly([] { return Future<void>::foobar; });
}
// ============================================================================
--
<span class="quote">>clang test.cpp -std=gnu++11 -c</span >
test.cpp:18:37: error: no member named 'foobar' in 'Future<void>'
Firstly([] { return Future<void>::foobar; });
