Avoiding overriding the global operators new, delete

Hi everybody,

In one of my game modules, global operators new, delete cannot be overridden. To do this, in my module I can define a custom macro IMPLEMENT_MODULE (for example IMPLEMENT_MODULE2) where I will delete the line for overriding the operators new, delete:

#if IS_MONOLITHIC

#define IMPLEMENT_MODULE2( ModuleImplClass, ModuleName ) \
		static FStaticallyLinkedModuleRegistrant< ModuleImplClass > ModuleRegistrant##ModuleName( TEXT(#ModuleName) ); \
		extern "C" void IMPLEMENT_MODULE_##ModuleName() { } \
		PER_MODULE_BOILERPLATE_ANYLINK(ModuleImplClass, ModuleName)

#else

#define IMPLEMENT_MODULE2( ModuleImplClass, ModuleName ) \
		extern "C" DLLEXPORT IModuleInterface* InitializeModule() \
		{ \
			return new ModuleImplClass(); \
		} \
		extern "C" void IMPLEMENT_MODULE_##ModuleName() { } \
		UE4_VISUALIZERS_HELPERS \
		//REPLACEMENT_OPERATOR_NEW_AND_DELETE \
		PER_MODULE_BOILERPLATE_ANYLINK(ModuleImplClass, ModuleName)

#endif //IS_MONOLITHIC

And now I announce the implementation of my module:

IMPLEMENT_MODULE2(FMyModuleModule, MyModule)

This seems to work, provided I don’t use UObject-inherited objects in this module. But I don’t really understand why the global operators new and delete are overridden, so I suspect there may be potential problems.

Can I use this code and what potential problems might arise when using it?
