[omniORB] CORBA::String_var and CORBA::string_alloc (again!)

[Bruce Visscher]

I hate to bring this up again, but...

>From the src/lib/omniORB2(!) directory of an omniORB 3 directory (hope
you can translate the VMSese):

search [...]*.cc string_alloc,string_var/match=and

******************************
OMNI3ROOT:[SRC.LIB.OMNIORB2.DYNAMIC]REQUEST.CC;1

              CORBA::String_var repoId(CORBA::string_alloc(repoIdLen -
1));

******************************
OMNI3ROOT:[SRC.LIB.OMNIORB2.ORBCORE]CORBAORB.CC;1

          CORBA::String_var id  = CORBA::string_alloc(slen);
          CORBA::String_var uri = CORBA::string_alloc(slen);

******************************
OMNI3ROOT:[SRC.LIB.OMNIORB2.ORBCORE]INITFILE.CC;1

      CORBA::String_var id  = CORBA::string_alloc(slen);
      CORBA::String_var uri = CORBA::string_alloc(slen);

The first occurence is correct.  The others are wrong for reasons that
I've beaten to death in the past.  Note that I haven't yet experienced
problems, but unless something has changed that I'm not aware of, this
won't work.  The reason is that the CORBA::String_var type does not have
reasonable copy semantics.

Sorry for not catching this sooner.  It's been a while since I checked
this.

(!) Why was src/lib/omniORB2 never renamed to omniORB3?
