Assertion CalleeType->isFunctionPointerType() && "Call must have function pointer type!" failed #97770
Description
This came up during reduction of #96623.
Code (https://godbolt.org/z/doefrKzeh):
struct BasicPersistent {
BasicPersistent(const char * = __builtin_FUNCTION());
};
template <typename>
decltype(BasicPersistent{}) construct_at(int) {
return {};
}
template <typename>
static void construct() {
construct_at<int>(0);
}
void AddObjectToUpArray() {
construct<int>();
