| // 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. |
