clang version 9.0.1
Target: x86_64-apple-darwin19.3.0
I am attaching preprocessed and delta-reduced sources. To illustrate, a
non-preprocessed testcase is
---
#include <memory>
template <class NodePtr>
union basic_raii_node_ptr_deleter {
using inode256_type = typename NodePtr::inode256_type;
const std::unique_ptr<inode256_type> node_256;
~basic_raii_node_ptr_deleter() {
node_256.template ~unique_ptr();
}
};
---
where <memory> is from Apple standard C++ headers.
