<pre>This warns, like it should:
thakis@thakis:~/src/chrome/src$ cat test.cc
#include <memory>
struct S {
virtual void f() {}
};
struct T : public S {
};
void f(S* s) {
delete s;
}
thakis@thakis:~/src/chrome/src$
third_party/llvm-build/Release+Asserts/bin/clang -c test.cc -Wall -std=c++11
test.cc:11:3: warning: delete called on non-final 'S' that has virtual
functions but non-virtual destructor [-Wdelete-non-virtual-dtor]
delete s;
^
1 warning generated.
But this doesn't:
thakis@thakis:~/src/chrome/src$ cat test.cc
#include <memory>
struct S {
virtual void f() {}
};
struct T : public S {
};
void f() {
std::unique_ptr<S> s;
}
thakis@thakis:~/src/chrome/src$
third_party/llvm-build/Release+Asserts/bin/clang -c test.cc -Wall -std=c++11
It should.</pre>
