[omniORB] string intialization

[Dominic Chorafakis XE41 ext. 9049]

Hi,

I have a question about the implementation of the
class String_member.

If I define:  typedef sequence?string>  MySeq;
and in a client I do:

{
  MySeq s;
  s.length(1);
  s[0] = "Hello";
  ...
 }

the compiler (GNU) interpretes "Hello" as a char *
(not const char *).
As a result, the String_member assignment operator
in CORBA.h
line 213 is invoked:

inline String_member? operator= (char *s) {
  if (_ptr) {
    string_free(_ptr);
    _ptr = 0;
  }
  _ptr = s;
  return *this;
}
When the variable "MySeq  s"  goes out of scope,
the destructor of String_member
invokes string_free to deallocate _ptr , which
should not be done.
The problem is solved by doing s[0] = (const char
*)"Hello", which actually
allocates a buffer for _ptr and copies the string.

Is it intentional that the above assignment
operator just copies the pointer ?  If so,
should the class String_member not call
string_free ONLY if it has allocated _ptr
by a call to string_alloc ?

Sorry if this topic is already covered in the
mailing archive but I have some
problems searching it.

Thanks in advance.
