why destructor function called twice

Hi all,
something wrong with my code, it seems that the destructor function

Tip: Keep pulling lines, functions, and classes out of that until it
reproduces the bug in the minimum lines possible.

Only then post the sample code.

But that tip runs the risk of exposing the bug for you...

This is most likely not the cause of your problem, but your program is
ill-formed.

Any identifier with a leading underscore followed by an uppercase letter
is reserved to the implementation -- you may not use it for your own
purposes.

Your code is too large for any sane person to want to diagnose.
Cut it down.

Without bothering to look to carefully, absent any explicit
destructor calls, my guess is that your destructor IS NOT
being called twice, but in fact you're missing the fact that
a temporary object is being constructed somewhere and you're
seeing that object being destructed.

Check all your copy-assignment operatosr and copy constructors
for proper operation. Remember things are put into and moved
around standard containers by copying.

I note specifically that you are violating the "rule of three."
While you have copy constructors and destuctors, your classes
lack a definition of an assignment operator. This is particularly
bad since you use assignment all over the place in your code.

Do you mean Fixture::~Fixtu re() ? Then there is nothing wrong with your
code: you have two such objects.
