[Laszlo-dev] How should DHTML handle these lzunit smokecheck expected errors?

[P T Withington]

Yes, there is.  I think I had code in the compiler to deal with this,  
but I disabled it because it made the overhead in debug builds too  
onerous.  Is the browser halting because of the reference to  
undefined (which I thought should be protected already) or because we  
are trying to de-reference undefined (which is the check that I have  
turned off)?
