How to debug android native crash with anonymous and unknown backtrace?

cocos2d-x
#21

That I completely understand, but what I do not understand is how that applies to complex types like c3b?

How can cc.c3b(0, 0, 0) be nil, since it’s a valid object, as is cc.c3b(255, 255, 255). They are neither nil, nor false. Wouldn’t local color = cc.c3b(0, 0, 0) or cc.c3b(255, 255, 255) result in undefined behavior (which is what you seem to be experiencing)?

#22

c3b is a function defined in Cocos2d.lua which returns a table.

function cc.c3b( _r,_g,_b )
    return { r = _r, g = _g, b = _b }
end

since table value is not nil or false, the statement local color = cc.c3b(0, 0, 0) or cc.c3b(255, 255, 255) should aways result with cc.c3b(0, 0, 0).
So we wonder is there any problem in that luajit library.

#23

Oh right, so it has nothing to do with the actual values of r,g,b in the c3b object, and you’re simply testing the existence of the object, so local color = cc.c3b(0, 0, 0) or cc.c3b(255, 255, 255) is just a test case.
