D.gnu - bug: "unsigned"

reply KennyB <funisher gmail.com> writes:
I was converting C++ code and I just did this by accident:

class A
{
     this(bool lala = false, unsigned ubyte lala2)
     {

     }
}

it segfaults gdc. I'm on gentoo. I do not have the ability to test it on 
dmd, so I cannot compare if this is a bug that was fixed in dmd 113.

If someone can verify that this exists on dmd also, then post it to the 
bugs forum.

Confirmed on Linux:

dmd 0.113 segfaults on this code also.

Interestingly, if you remove the default argument for "lala", the compiler
emits errors instead of segfaulting.

yeah I know, lol.
If you take out anything, then it just gives an error. This is probably 
one of the most obscure bugs I've found in a while.

D really needs a bugzilla :) -- I LOVE the one at bugs.gentoo.org.

Yeah,
but it's not like it hasn't been suggested before...

Currently we just post to the newsgroups and scribble
a few lines on the Wiki4D, and then just ignore it.

Sad.

DOH! I was kinda being sarcastic ... If I was serious, I would have 
searched, but still... I read those posts, and I didn't see Walter 
respond to any, so it appears that he doesn't want/need bugzilla. Oh, 
well, I guess a bugs newsgroup is just as good. I would however much 
prefer a moderated forum though, so irrelevant posts (such as this one) 
can be moved.

I know I'm really hijacking the topic here, but what if the D community 
setup a bugzilla, but the focus wasn't to post bugs, but to post 
patches? Perhaps if enough patches get posted, Walter will start merging 
them and it could save him some time searching for the bugs. I know I 
would be more than willing to start picking through the dmd source for bugs.

Since I'm kinda new, I should probably shut up :)

peace.

Walter has stated earlier that he doesn't want a bug database (yet?)

Actually, a lot of the bugs posted *do* find their ways into DMD...

This is how this digitalmars.D.bugs newsgroup works, with attachments.

On the contrary, D needs all the help and suggestions it can get!

But the currently the newsgroups holds all the ideas and discussions
and code and whatnot, and Wiki4D summarizes them up into topics:

http://www.prowiki.org/wiki4d/wiki.cgi?PendingPeeves
http://www.prowiki.org/wiki4d/wiki.cgi?FeatureRequestList

http://www.prowiki.org/wiki4d/wiki.cgi?BooleanNotEquBit
http://www.prowiki.org/wiki4d/wiki.cgi?UnicodeIssues

Somewhat crude "database/repository", but in works in the interim.

I imagine dsource.org will have a couple of Trac[1] projects for this 
purpose.  One for DMD and one for Phobos, in addition to all of the 
other projects found there.  You can open tickets and attach patches or 
have a discussion thread.  It's not Bugzilla yet, but Trac is showing 
promise.  If I could only get the developers to keep working on it 
instead of having to hack it around myself...

It's obviously an dmd frontend bug, but it's also quite not D (and not 
even C++ AFAIK). I think the docs somewhere mention that only trailing 
parameters can have default values, which is quite logical. If everyone 
was aware of this, I'm sorry for being pedantic :)
