RE: Destructor problems

That's the problem! :-)
I'm running under a CDF environment so the answer is no! :-( Many data members point to CDF classes!
In addition to that I'm getting errors using gdb because some libraries (FORTRAN) are not recognised! :-(
This is why I'm asking for ANY idea!
I'm completely lost! :-)))

Only 3 things are sure:

- it crashes at the first delete occurrence
- the TV0 instance is correctly created
- the job runs if I remove the delete but obviously dies because the

  instances rapidly fill up the memory

This is why I'm quite sure that it's something related to the dtor!

Bye...
