G++ produces a warning for the following sample, whereas clang does not:

int main() {
char buf[5];
__builtin___sprintf_chk(buf, 0, __builtin_object_size(buf, 0), "%s",
"foobar");
}
$ g++ foo.cpp
warning: call to int __builtin___sprintf_chk(char*, int, long unsigned int,
const char*, ...) will always overflow destination buffer [enabled by default]

"foobar");
$ clang++ foo.cpp
