I copied your program and added a return for clarity:

#include <string>
#include <vector>

int main() {
  std::string s1("foo");
  std::string s2("bar");
  std::string s3("baz");

  std::vector<std::string> strings;
  strings.push_back(s1);
  strings.push_back(s2);
  strings.push_back(s3);

  return 0;
}

so when on the "return 0" statement:

12	  strings.push_back(s3);
(gdb) 
14	  return 0;
(gdb) p strings
$1 = std::vector of length 3, capacity 4 = {"foo", "bar", "baz"}

But once past that:

(gdb) n

15	}
(gdb) p strings
$2 = 0


I think the strings were  garbage collected in your original case but not the
encapsulating vector. What's your opinion?

On the printed garbage, what you are seeing also is the string printer trying to
print just random memory. There's another bug relating to this:
