You are right in that egcs did a copy using the copy constructor.
This behaviour is different from other compilers:

As Lu has pointed out, Sun's CC 4.2 does not invoke the copy constructor. 

DEC C++ v 6.0 does not invoke the copy constructor (but DEC C++ v 5.6 does).

g++ 2.7.2 invoke the copy constructor but miss out one call to the

I do not know which is suppose to be the standard conforming behaviour.

Just another minor point that can catch the unawared I suppose..
