Memory leak in GCTAObservation on Mac OS X dependent on m_object member placement

Description
There is a memory leak in GCTAObservation that appears on Mac OS X systems and that relates to the placement of the m_object data member. I could so far not find any reason for this memory leak.
This feature is to keep track of the problem, needing a deeper investigation using for example valgrind.
For the moment, the code compiles well by moving m_object down in the list. This is of course only a kluge and not at all satisfactory.
Recurrence
No recurrence.

A valgrind analysis of test_CTA gave the following result:

This one turns out to be a try-catch construction for an out of bound test.

At this point I changed again the order of the members in GCTAObservation to see whether the modifications had any effect. However they did not, and I still get the memory leak problem.
I therefore apply now valgrind on the code with the problematic member order.
