robertlzj commented 2 years ago

Hi, test with test_alien.lua will fail on each callback

H:\TDDOWNLOAD\alien\alien-0.7.1\tests\test_alien.lua:48: bad argument #4 to 'callback' (string expected, got userdata)
stack traceback:
    [C]: in function 'alien_c.callback'
    H:\TDDOWNLOAD\alien\alien-0.7.1\tests\test_alien.lua:48: in main chunk
    [C]: in ?

where the code is local cb = alien.callback(callback, "int", "int"). Lua 5.3 x32, Win10
