It would be helpful if you explained what it was you were trying to
achieve. What is this return_attributes function?  Is it the
implementation of a CORBA operation?  Do you have a good reason for
making the component_attr sequence global?

The CORBA memory management rules are really very simple in this
respect (not in others). If this is a CORBA function, then it is the
caller's responsibility to free the returned sequence. It is a memory
error to do the delete at the start of return_attributes. By the time
that is reached, the sequence will have already been deleted.

Cheers,

Duncan.
