Building master branch crashes on Apple M1

[fingolfin]

is building current Julia master crashing for anyone else? (i.e. commit aae68a5, on : macOS 12.2 (21D49) on Apple M1 Max, Xcode 13.2.1).

It builds fine for me on Ubuntu x86.

Facing the same issue on an M1 MacBook Air, macOS 12.2. XCode 13.2 as well.

Got the same issue and am bisecting, there were also a bunch of warnings added that weren't present before so let's see.

[gbaraldi]

f090992 is the guilty commit according to bisect from #43852. Also a bunch of

./julia.h:397:9: warning: anonymous types declared in an anonymous union are an extension [-Wnested-anon-types]
       struct {
       ^

warnings appeared.

[giordano]

That's not a segfault though, is it?

[fingolfin]

Indeed it isn't

[ngam]

@fingolfin nice to see you here too :)

I am wondering if this is by design or a rule of thumb about building julia on new hardware (e.g. M1 Macs) or in general --- 1.7.2 works fine (a lot of tests still fail if you attempt run "all"... ) but master branch bombs (I think the error I get is identical to the above)

Oh noooo, @Keno 😢 I actually tried to build the master branch just to test this PR 😆

This platforms is currently in Tier 3 of support, this means there is currently no CI for aarch64-apple-darwin, so the failure couldn't be caught during the review of the pull request.

No, no I understand that --- to clarify, I meant: usually the "tagged" items are like guaranteed, but master isn't it exactly like that since it is not a release. Or do we consider master stable enough as almost like a pseudo-release?

[ngam]

Then again M1 shouldn't be considered stable at all, I guess. But in general for other hardware, master vis-a-vis tags?

[giordano]

Who said otherwise?

Not sure what that means.

Don't worry about it 😄 I am glad it wasn't just me, hopefully we will be able to test that PR soon since it seemed pretty impressive!
