In C++03 see 21.3.5.3 [lib.string.assign] paragraph 6 where 

string::assign(const char* s, size_t n) is defined to return

assign( string(s, n) ) and that constructor:



Constructs an object of class basic_string and determines its initial string

value from the array of charT of length n whose first element is designated by

s, 



In C++0x the requirement is explicit, [string::assign] paragraph 8 says



Requires: s points to an array of at least n elements of charT.
