Yes, still a use-after-free. There are a few easy ways to verify this. One, it
crashes if you change "struct String" to allocate storage on the heap, e.g.:
struct String {
char *content;
String (const String& a) {
content = new char[1000000];
strcpy(content, a.content);
}
String (const char* a) {
content = new char[1000000];
strcpy(content, a);
}
operator const char* () const {
return content;
}
~String() { delete content; }
};
Two, if you build with -fsanitize=address, you'll get a "stack-use-after-scope"
error.
