+//  This tests a bug when an exception is thrown in 
+// sc_module::sc_module() for a dynamically allocated sc_module 
+//  object. We are calling sc_module::end_module() on a module that has 
+// already been deleted. The scenario runs like this: 
+// 
+// a) the sc_module constructor is entered
+// b) the exception is thrown
+// c) the exception processor deletes the storage for the sc_module 
+// d) the stack is unrolled causing the sc_module_name instance to be deleted
+// e) ~sc_module_name() calls end_module() with its pointer to the sc_module
+// f) because the sc_module has been deleted its storage is corrupted, 
+// either by linking it to a free space chain, or by reuse of some sort
+// g) the m_simc field is garbage
+// h) the m_object_manager field is also garbage
+// i) an exception occurs
+// 
+// This does not happen for automatic sc_module instances since the 
+// storage for the module is not reclaimed its just part of the stack. 
+// 
+// I am fixing this by having the destructor for sc_module clear the 
+// module pointer in its sc_module_name instance. That cuts things at 
+// step (e) above, since the pointer will be null if the module has 
+// already been deleted. To make sure the module stack is okay, I call 
+// end-module() in ~sc_module in the case where there is an 
+// sc_module_name pointer lying around.
