<pre>Compiling the following code results in an assert.
$ cat t1.cpp
template<typename T>
void func() {
enum class foo { a, b };
auto bar = [](foo f = foo::a) { return f; };
auto tmp = bar();
}
int main() {
func<int>();
}
$ clang++ -std=c++14 -c t1.cpp
Assertion failed: ((isGenericMethod || ((*I)->isVariablyModifiedType() ||
(*I).getNonReferenceType()->isObjCRetainableType() || getContext()
.getCanonicalType((*I).getNonReferenceType()) .getTypePtr() == getContext()
.getCanonicalType((*Arg)->getType()) .getTypePtr())) && "type mismatch in call
argument!"), function EmitCallArgs, file
llvm/tools/clang/lib/CodeGen/CodeGenFunction.h, line 3332.
It doesn't assert if I move the definition of enum foo out of func.</pre>
