<pre>The following code causes a crash with an assert failure no Clang, rather than
producing a compile error:
clang::ExprResult clang::Sema::CheckConvertedConstantExpression(clang::Expr*,
clang::QualType, llvm::APSInt&, clang::Sema::CCEKind): Assertion
`T->isIntegralOrEnumerationType() && "unexpected converted const type"' failed.
Expected:
error: statement requires expression of integer type ('NOT_AN_INTEGRAL_TYPE'
invalid)
switch(Bad) {
=================================
struct NOT_AN_INTEGRAL_TYPE { };
template<typename T> struct foo
{
NOT_AN_INTEGRAL_TYPE Bad;
void run();
};
template<typename T> void foo<T>::run() {
switch(Bad) {
case 0: break; // Literally breaks Clang.
}
}</pre>
