@@ -178,3 +178,41 @@ to store which other object subscribed to it. However, by thinking a
little bit about which objects use the one that is presently
destructed, one usually quite quickly finds out where the problem is.

+Versions after deal.II 3.0 give slightly better
+information in that they are at least able to tell which object is
+destructed. The output then looks like this:

+--------------------------------------------------------
+An error occurred in line <20> of file

+This tells us, that the object that is presently deleted is of type
+t4FEQ21i2. Of course, this is not the actual name of the
+class, but what the C++ run time library returns as name; it is in
+fact the mangled name of the class, and you can get back the
+true class name by running the program c++filt on that
+name, which then returns FEQ2<2>. (The mangled name
+can be read without c++filt in the following way: the
+first letter tells us that the class name is a template, the second
+that the name of the class name without template arguments is four
+characters; we then already have FEQ2<...>. After
+the class name, the next character tells us that the class has one
+template parameter, the ``i'' indicates that it is of type ``int'' and
+finally that it has the value ``2''. Thus, we arrive at
+FEQ2<2>.)
