After a quick look into it, I suggest that you get rid of malloc() usage. You are using 'delete' on memory that has been malloc'ed - that must not happen. Then about 'delete', you only can delete something that has been allocated by 'new', consider [code] class a { public: …

Emphasizing line #48, the [ICODE]mc[/ICODE] object is on stack (i.e. not allocated by new), so when it goes out of scope, its destructor gets called automatically. Generally you don't call destructors, those get called via delete or automatically in case of stack objects.
