Log of clang run
The following code crashes clang r209002 when being compiled with -g:
template <bool>
struct enable_if { using type = void; };
template <typename L, typename enable_if<true>::type* = nullptr>
static void testVoidIf(L&&) { }
int main()
{
testVoidIf([]() {});
}
This results in (full log attached):
% ~/LLVM/build/Release+Asserts/bin/clang -std=c++11 -g clang.cpp
