Why does a switch break cause a segmentation fault

[eric at makechip.com]

Shouldn't (stream == null) be (stream is null)?

Subject: Why does a switch break cause a segmentation fault 

Hey, I just happened to be writing a program in D an stumbled 
upon a bug, that causes it to terminate after receiving a SEGV 
signal, nothing wierd so far but it looks everything I tried 
shows it is the break statement inside of a switch. 
It seems to have a relatively random chance of occuring, and also 
somewhat dependant on the compiler, and build mode used. 
I'm short on time so instead of rewriting my SO post I will just 
link it. 

Here!

Hope someone can help!
