segmentation fault in cppunit at cleanup time - c++

Question

CPPUNIT crashes after execution of my program while returning from main during the cleanup phase. TestWrapping's dtor calls TestSuite's dtor which then calls deleteContents which triggers the test cases cleanup.
What's weird is that the TestSuite's dtor gets called twice ?
This follows the successful execution of 6 test cases. Any idea on how this can be avoided ?
Program terminated with signal 11, Segmentation fault.

I'm hoping your code isn't explicitly calling these objects' destructors, but is either calling delete on a pointer to them, or else they are going out of scope and the compiler is automatically calling their destructors. Assuming you're not explicitly calling destructors.....
It would seem that your TestSuite object either does a delete this or else it contains a pointer to itself (or obtains a pointer to itself somehow within deleteContents()) and then calls delete on that pointer. You haven't posted the source for your TestSuite class (and specifically its deleteContents() method), but that's my guess, not having seen the code.
