>Description:
A segmentation fault is raised in the destructor of the class which inherited and virtual in a child class.

This occurs when throwing the child class as an exception and catching the parent class as a reference.

When not virtual is not specified in the inhertence then the sample works, or when the catch is changed from a reference to a pointer.

However these are unacceptable solutions, since the case that triggered this issue is more complex.

Under MS Visual C++ 6.0 & Borland C++ there are no faults.
