I just tried this using dmd v.150 and Windows XP and it works fine.

Lucky you. But I am really not interested in wasting my time by working in a
buggy language nor by cutting my source down to the essential raising that bug.

In fact the control flow took even the wrong path:

switch( value){
case SOMECONST:
assert( false); // not executed
break;
case SOMEOTHERCONST:
assert( value == SOMEOTHERCONST); // failed
}

It's your loss. Can you please at least post the code here so we can  
figure out whats going on.

Of course you mean 'buggy compiler' and not 'buggy language', but that
aside for now ... dmd v0.150 is *BETA* --- it is expected to have bugs in
it still and that's why we are trying to find and fix them. 

If you don't want to help fix the compiler then fine, go away and come back
later when other's have done the good deeds. 

My earlier reply was trying to say that the compiler is working in at least
one environment so I assume you are not working in Windows or not using
v0.150, or your code example is faulty because it doesn't exhibit the
problem you reported. 
 

 In fact the control flow took even the wrong path:
 
 switch( value){
 case SOMECONST:
 assert( false); // not executed
 break;
 case SOMEOTHERCONST:
 assert( value == SOMEOTHERCONST); // failed
 }


If you actually want this resolved, try showing us a complete (compilable)
example that exhibits the problem. Until then, I'm assuming you have made a
coding error rather than dmd is at fault. Prove otherwise.

I work for money, not for reputation. Assume what you want, especially that the

If you've got nothing constructive to add stop posting, or, keep posting  
if it makes you happy just be prepared to be ignored as a "troll". Given  
the inflamatory nature of your post I am surprised you only got 1  
agressive response.

As Derek politely pointed out, you didn't post a complete example. Without  
a complete example there is no way for us to help you, in which case why  
post at all? (unless you're simply trolling?).

I've done my best to produce a complete example, here is what I came up  
with:

alias int SomeType;

SomeType f(){
	SomeType result;
	result = 1;
	return result;
}

void g(){
	SomeType value;
	value = f();	
	switch(value){
	case 1:
		assert(value == 1); // fails !!!
	}
}

void main()
{
	g();
}

I assume you meant for us to replace SOMECONST with an integer constant,  
if not, let me know what it was because nothing else I tried would  
compile. Using the code above I get no assert, which is the correct  
behaviour.

I also tried this example with s/1/SOMECONST/ and adding this block at the 
top:

//alias char[] SomeType;
//const char[] SOMECONST = "abcde";
alias int SomeType;
const int SOMECONST = 1;

Neither the char[] nor the int version assert for me.

I used my gdc 0.18 pre-release as well as dmd 0.148 and 0.149, all on 
linux.  I haven't grabbed 0.150 but Derek reported an inability to 
reproduce the problem with 0.150 on xp earlier in the thread.

So, debugger, despite your arrogance and disdane for the rest of the D 
community, there's interesting in fixing bugs in the D compiler both from 
it's primary author and it's supporting team.  If you'd be so kind as to 
point out the difference between these test cases and your as-of-yet 
undisclosed repro case, it'd be appreciated.  If you'd also point out what 
compiler and platform you used that'd help too.

Thanks,

Wow... I am... uh... speechless... lol!

This guy has some unusually "witty" retorts. It makes me wonder... were 
these saved for just such an occasion or were they spontaneously 
contrived on the spur of the moment? It's not often we come across such 
a verbally gifted troll.  I'm at a loss for what to do now except laugh!

Interesting, really! Although, it's a wonder he even posted.  He 
obviously had no interest in being helped here, so why are guys 
bothering to act all serious and offended?  Wasn't his intent obvious 
from the beginning? (Why am I for that matter bothering to post this? 
Hmmm...pardon me... must be the stupid pill I took)

Welcome to D, debugger; here lies a land full of people who bash bugs, 
debuggerlessly, and they do so with finesse, cheerfulness, and even 
perhaps a modicum of selflessness!(okay, maybe not all the time)  You'll 
get along fine with them... honest!

No need to send me away.

Everyonce in a while I visit one of these open source packs and their habits did
not change during time.

In essence they are like lepers lingering at the outskirts of the town. For
years Jesus walks by and nobody takes notice of each other.

Then one day Jesus spends them bread and plenty of fish.

They are not content because they get the food in baskets, but without dishes,
"bad style" they say.

Next day they know Jesus and as he walks by he says: "Look over there. There are
fructiferous fig trees. They belong to nobody."

Then a mourning started: "Yesterday he gave us food and today he gives us
words---that bastard."

Not everyone here is "open source". In fact, even the DMD compiler backend  
is closed source.

	Why? We have yet to see any evidence that this bug really exists (as opposed

it being a bug in your program).

Actually, this is a good sign for D - you know you've hit general circulation
when you get wack-jobs like this guy posting like he has.

Either way when he sees the thread go a day or two with no response he'll
probably jump in again, and when that happens, I think it's time we stop wasting
our time and quit responding. I know this is my first (and last) post on the
