Infinite call to gen_destructor

[raffopazzo]

I have lost the test case now but gen_destructor_call() in

depc/dep0/lib/05_llvmgen/src/gen_body.cpp

Lines 266 to 287 in 5b5a83f

	static void gen_destructor_call(
	global_ctx_t& global,
	local_ctx_t& local,
	llvm::IRBuilder<>& builder,
	llvm::Value* const value,
	typecheck::expr_t const& type)
	{
	auto destructor = global.get_destructor(type);
	if (not destructor)
	{
	destructor = gen_destructor(global, type);
	global.store_destructor(type, *destructor);
	}
	if (auto const properties = get_properties_if_array(type))
	{
	auto const size = gen_array_total_size(global, local, builder, *properties);
	auto const call = builder.CreateCall(destructor->type, destructor->func, {value, size});
	call->addParamAttr(1, llvm::Attribute::ZExt);
	}
	else
	builder.CreateCall(destructor->type, destructor->func, {value});
	}

may end up in an infinite recursion calling itself. I think the test was involving a tree, which is not surprising since deleting a node requires deleting its nodes.
