D - Dernel: how does exception handling work?

Hi, I had a problem with my code bombing and I found out that it was a  
problem with a "switch" statement not having a "default" choice. The D  
compiler inserted code that in this case a SwitchError is thrown.

What do I need to support, that this throw stuff works? What does the D  
compiler expect to find (exception tables, etc.)?

I don't understand the question. But to fix the problem with the switch, add
a default case.

Hi Walter, ;-) yes I did this. The problem I get is a stack problem, ESP  
isn't set right or so. My question is: Do I need to support something  
special (interrupt, exception handling of the Intel hardware etc.) so that  
the D compiler generated exception handling code works?

Exception handling is done differently under win32 and linux. The linux
version is more OS independent, so if doing a D kernel, I'd go that route.
