Irrlicht Engine

Hi,
I've implemented LUA script (using LUABIND) in my project. to do that I had to build Irrlicht again with RTTI (RealTime Type Info) enabled.

since I built Irrlicht with RTTI enabled I get this error on using driver->getTexture or driver->addTexture commands :
It's funny, it wouldn't be any error if getTexture doesn't find the texture file! just my model stays white! but the error occurs when it finds the texture file.

I didn't have this problem before.

I tried several things and I'm almost sure that RTTI is my problem.

am I right about the RTTI? does it have anything to do with Irrlicht Textures?
how can I fix this?

No, there shouldn't be any intereference with RTTI. Moreover, reading a 0x1 is very strange, as a failed dynamic cast would return 0x0 instead. I'd bet that you still have some old object files lurking around, which do not have the RTTI compiled in, but the run-time assumes so. This can lead to very severe crashes of this kind.
