getting a resource multiple times causes side effects

[Andre-LA]

Test code:

-- in nelua
##[[
  TICO = {
    L = '../../tinycoffee/build',
    I = {
      include = "../../tinycoffee/include",
      external = "../../tinycoffee/external"
    },
  }
]]

require 'tico'

local nelua_argc: cint <cimport, nodecl>
local nelua_argv: *[0]cstring <cimport, nodecl>
local config = tico.config_load('project.tico', nelua_argc, nelua_argv)
--local config = tico.config_init('mytest', 800, 600, nelua_argc, nelua_argv)

tico.init(config)

for i = 1, 10 do
  local res = tico.plugin_resources_get('image', 'lunarlander')
end

while not tico.window_should_close() do
  tico.update()

  tico.begin_draw()
    tico.graphics_clear(tico.BG)

  tico.end_draw()
end

tico.terminate()

(this generates this C code)

// some typedefs:
static char __strlit1[13] = "project.tico";
typedef char** nlcstring_ptr;
typedef tc_Resource* tc_Resource_ptr;
static char __strlit2[6] = "image";
static char __strlit3[12] = "lunarlander";
static tc_Color tico_tico_BG = {75U, 90U, 90U, 255U};
/// [...]
testes_config = tico_config_load(__strlit1, nelua_argc, (nlcstring_ptr)nelua_argv);
  tico_init(&testes_config);
  for(int64_t i = 1; i <= 10; i = i + 1) {
    tc_Resource_ptr res = tico_plugin_resources_get(__strlit2, __strlit3);
  }
  while(!tico_window_should_close()) {
    tico_update();
    tico_begin_draw();
    tico_graphics_clear(tico_tico_BG);
    tico_end_draw();
  }
  tico_terminate();
  return 0;
  // [...]

Behaviour

Running this code will give this error at exit:

[...]

However, changing the for count will create other errors, for instance, changing from 10 to 13 will give this error at startup:

I remember that there is another one which gives an error on miniaudio, which also makes the game's sound a little weird.
