AFAIK, this is not a regression in Xcode, but a new warning for a bad situation
that was previously unreported.

The code still builds, but the pointers that dmd generates in the object files
were misaligned.

It is a regression of DMD, because older versions of DMD did not generate
misaligned data.

I think we can fix in the stable branch, and move on here.

Fair enough.

I think that's completely fine. However, we don't know when the next release
(major or minor) will occur, and Martin (our current release manager) hasn't
been seen online the past few days.

It's thousands of pages of warnings for one compile, using the out-of-the-box
experience of how to download and try D, as described on the main website. If
you get dub and type 'dub run dscanner', for example, thousands of pages of
warnings. Also, it never finished building for me and I had to press Ctrl-C on
the terminal. I'm focusing on the new user who decides to try D one day. Whose
only sin, apparently, is that he bought a mac. Or that he chose to use D, for
some reason.

What's wrong with Steven Schveighoffer's suggestion about including it in the
next release for the stable branch? That seemed like a good compromise. 

I do think your focus is wrong, and that you should consider thinking of D as a
product that you can help to deliver to customers, whether they pay for it or
not. Something that you can be proud to be associated with. But that's a
philosophical issue, and a hard one, and a long conversation.

Bad analogy. It is your choice to use Apple products, your choice to update
Xcode, and your choice to (instead of using a workaround) attempt to escalate
the issue, here, on D's bugtracker, even though the breaking change was in
Xcode, not D.

> A good business focuses on the customer.

Well... would you like a refund? Luckily for us, D is not a business, it's an
open-source project.

1. Only Apple users.
2. "Hurting"? Isn't it just warnings?

We are not going to make an exception for our release process for a LINKER
WARNING.

All in all, I definitely don't see any reason to treat this issue with the
urgency you demand, and I don't think the tone of your communication is of any
help to anyone.

There are multiple workarounds available at your disposal:

- Build D from git
- Use a nightly version of D (https://nightlies.dlang.org/dmd-nightly/)
- Filter out the linker warnings locally
- Downgrade Xcode
- Use a different operating system

Considering the fix was already merged, please make use of one of the
workarounds above and stop exaggerating the problem.

Okay, makes sense. Cherry picking pull:

If you're running a business, you wouldn't tell your customers, "Our supplier
crashed their truck, so we're not required to serve you." A good business
focuses on the customer. Maybe someone should bring this up with Apple and
Xcode, true. But Walter was able to fix it with a three line change to dmd, and
it's D users who are hurting.

Since the breaking change was in Xcode, it would be a regression in Xcode as
well, no? I'm not sure about the idea of D being required to treat regressions
in others' software with urgency.

Please, don't reopen bugs based on whether the fix is in a released compiler.

I agree the warnings are jarring and bad, and this should go into 2.074.1. But
the fix is already merged, and that's what the bug tracker should track. If you
want to make a difference here, create a PR to cherry pick the fix into the
stable branch so it's included when 2.074.1 beta process commences.

I guess I'll reopen this issue to make the point, now that I have an ally.
Again, I believe this is in effect a horrible regression, and the fix should be
patched to the main website ASAP.

I agree, the warnings are both alarming and a real nuisance. It would be worth
including this in a 2.074.1 patch release.

Well, 0xB, i.e. 11, is certainly not aligned.

I'm upping the importance on this. I literally get 20 pages of linker warnings
whenever I build. This seriously impedes any workflow I can have while using
dmd.

I saw that stack overflow article, However, it seems that it's an unrelated
software (firebase from google) which happens to cause the same issue as dmd.
At first I thought it said that Xcode 8.3 was to blame.

Hey, maybe they are secretly using D under the hood :)

Seeing the same behavior. Occurs in most of my programs. DMD64 D Compiler
v2.073.1; Xcode 8.3, Build version 8E162. Does not occur with LDC.
