[Swig-devel] [Lua] Check unsigned arguments to be positive

[Jérôme P. <jer...@sy...>]

In Lua binding, number arguments are directly casted to target type, like 
this:
$1 = ($type)lua_tonumber(L, $input);

There is no check for unsigned numbers. So, for exemple:
Lua> getElementInMyVector(-1)
... crash ...

I suggest to use patch in attachment to correct this behaviour. Nevertheless, 
I am not familiar with Swig macros, so it may exist better way to correct 
this.


Cheers,
