Hello
I'm using g++ for a project where I have to store serialized data as a
char*. Of course, these serialized bits are likely to contain NULL
characters which implies that NULL-terminating strings obviously are a
bad choice. Unfortunately, storing the information as char* is
predetermined. This means I serialize the objects, process them as
std::string and then store them as char*. When I try to recover the
std::string, the behaviour is kind of strange (consider the code snippet
below as an example):
const char* hello = "hel\0lo";
std::string s(hello, 6);
std::cout << "s.length() = " << s.length() << '\n';
std::cout << "s = \"" << s << "\"\n";
prints 'hel' on my machine running g++ v4.6.1 (which apt pretends to be
up to date) while it prints 'hello' on a stackoverflow contributor's
machine running version 4.4.5. (For the full question see
stackoverflow.com/questions/15525208).
Is this a known issue - and does anyone know a workaround?
Any hints are very appreciated - TIA!
Cheers
Alex
