Hi,

Sorry. I use 3.00/06 on a RH6.1/i386 machine.

I think I observe the following :
	- if the globalWireInfo is == 0, then the constructor is called once
	- if the globalWireInfo is != 0 and is a pointer to a WireInfo
	  object, then the constructor is NOT called at all
Can you guarantee somehow that in case globalWireInfo is != 0 the
constructor will NEVER be called ?

That was my bug, sorry.
But it's interesting that in this case the constructor was called TWICE.

Let me ask the question - why do you need the reference to the pointer ?
This makes the problem that one cannot use "this" there (often "this" is
not a variable).
