 #include <iostream> // for std::cout
 #include <string>
 
 int main()
 {
   std::string blanks( 3, '\0');
   std::string foo = "hello";
   foo += blanks;
   foo += "world\n";
   std::cout << bar;
   return 0;
 }
 
 This should print "hello\0\0\0world\n" to std::cout,
 but by sending bar.c_str(), all that gets sent is "hello".

 Yes, good catch.

 Do you have a small testcase?
