ECS_MODULE throws -> error: taking the address of a temporary object of type 'MODULE_NAME' [-Waddress-of-temporary]

[WEREMSOFT]

Describe the bug
I'm trying to create modules based on the example file 04_simple_module. I need to use C++

I added a .hhp file in the project, which is the following:

#pragma once
#include "flecs.h"

extern "C" {
    typedef float PositionX;
    typedef float PositionY;

    void MoveX(ecs_rows_t *rows) {
        static double phase = 0;
        static int offset = 0;
        ECS_COLUMN(rows, PositionX, p, 1);
        phase += 10 * rows->delta_time;
        for (int i = 0; i < rows->count; i++) {
            p[i] = sin(phase) * 100 + offset++;
        }
    }

    void MoveY(ecs_rows_t *rows) {
        static double phase = 0;
        static int offset = 0;
        ECS_COLUMN(rows, PositionY, p, 1);
        phase += 10 * rows->delta_time;
        for (int i = 0; i < rows->count; i++) {
            p[i] = cos(phase) * 100 + offset++;
        }
    }

    /* This type is used to store handles to everything that the module contains.
    * When the module is loaded, this type will be registered as component, and
    * added to the singleton entity so applications can access module handles from
    * anywhere. */
    typedef struct MoveModule {
        ECS_DECLARE_COMPONENT(PositionX);
        ECS_DECLARE_COMPONENT(PositionY);
        ECS_DECLARE_ENTITY(MoveX);
        ECS_DECLARE_ENTITY(MoveY);
    } MoveModule;

    /* This macro is used to declare variables that contain the handles inside the
    * module. It is invoked by the ECS_IMPORT macro to declare variables in the
    * scope where the macro is invoked so the contents of the module can be used
    * after the ECS_IMPORT macro. */
    #define MoveModuleImportHandles(handles)\
                ECS_IMPORT_COMPONENT(handles, PositionX);\
                ECS_IMPORT_COMPONENT(handles, PositionY);\
                ECS_IMPORT_ENTITY(handles, MoveX);\
                ECS_IMPORT_ENTITY(handles, MoveY);\

    void MoveModuleImport(
            ecs_world_t *world,
            int flags)
    {
        /* Define module */
        ECS_MODULE(world, MoveModule); // THIS LINE HAS THE ERROR

        /* Register components */
        ECS_COMPONENT(world, PositionX);
        ECS_COMPONENT(world, PositionY);

        /* Define a system called Move that is executed every frame, and subscribes
         * for the 'Position' and 'Velocity' components */
        ECS_SYSTEM(world, MoveX, EcsOnUpdate, PositionX);
        ECS_SYSTEM(world, MoveY, EcsOnUpdate, PositionY);

        /* Export handles to module contents */
        ECS_SET_COMPONENT(PositionX);
        ECS_SET_COMPONENT(PositionY);
        ECS_SET_ENTITY(MoveX);
        ECS_SET_ENTITY(MoveY);
    }
} 

But I have this error in the build:

To Reproduce

1. Create a program.
2. Create a module.
3. Try to include the module in the world.

Expected behavior
Handle the systems in the module as a unit.

Additional context
I'm trying to do it in C++, since I'm trying the framework SFML that is in C++. I'm using MacOS X Catalina.
It works well on C99.

Looks like nobody has ever tried creating a module in C++ before, I'll look into it!
