i686-w64-mingw32-gcc-nothreads build failure - Segmentation fault

[mmaenz (Michael Maenz)]

Trying to install port mingw-w64 in order to compile Valve's latest Proton. First time to try to compile on Catalina. Did everything what the CatalinaProblems Page suggested.

My specs

• macOS Catalina 10.15.3
• XCode 11.3.1
• Command Line Tools 11.3

Attached the last lines of the log with the error as the whole is very huge (~160MB). Saved the log, can send or upload it if valuable for further investigation. The error is explained in line 4, 18 and 21.

[mojca (Mojca Miklavec)]

Hmmm, I'm sorry, this one has apparently always been broken on 10.15 (​https://ports.macports.org/port/i686-w64-mingw32-gcc-nothreads/), but I never noticed it, we need some more "show me all my broken ports" functionality.

So we do have the ​full build logs on our build infrastructure.

Now, with

internal compiler error: Segmentation fault: 11

I'm somewhat clueless about what to do without upstream jumping in for help.

[mojca (Mojca Miklavec)]

Can someone with Catalina please check whether adding -fno-stack-check to configure.cflags-append helps? I'm not saying it does, just that it might be worth trying given how many troubles we had with other ports, see for example #59246 which is not the only one.

You need to make sure to recompile i686-w64-mingw32-gcc-bootstrap as well from source (make sure that it's not a binary from our buildbot) before trying to build this one.

Even if the compiler problem was fixed in the meantime, we might still be hit as we are still using an old bootstapped binary build with the buggy compiler.

[kencu (Ken)]

we need a crashlog to move forward.

[mojca (Mojca Miklavec)]

I didn't yet dare to update to 10.15 (I almost got my mac bricked by a regular security update and needed one hour on the phone with support to get it recovered via secret key combinations at boot time & some subsequent steps).

The bug seems to be fully reproducible, so if anyone is willing to look into it ... But before we do some serious analysis, it would really make sense to check if that known clang bug had anything to do with this. We've seen way too many segmentation faults as a consequence of buggy clang behaviour.

I can confirm xcode11 failed to built this on macOS Catalina regardless of deployment target or even overriding the SDK to 10.13 will still result in a failed compile.

I did a few changes to the Portfile that might not have been needed (I’ll edit the comment or comment again after work), I did blacklist XCode11 now building from source using macports clang-9 I got a completed build. The same blacklisting of XCode11 was applied to the X86_64 package and for good measure also onto the mingw-w64 meta package (not sure if it’s required or not)

I pre-installed clang-9.0 since it failed to installed due to a missing package when called via mingw-w64

Edit; I believe I’ve figured that out and will do a pull-request later that resolves the issue.

Just an FYI the mingw binutil conflict isn’t related and was caused by the xz version bump

[Gcenx]

@mojca the issue here isn't with the Portfile here exactly but the prebuilt packages.

Removed all ports, edited macports.conf and set buildfromsource always now i686-w64-mingw32-gcc-nothreads built without issue.

Can you be more specific? What error message did you get exactly?

I think you mean ​https://github.com/macports/macports-ports/pull/6449? But you closed it saying blacklisting wasn't what fixed it, it was just building everything from source that fixed it.

Can you be more specific? Which packages need to be rebuilt? When Catalina was first released, we of course built all of our packages for it with Xcode 11. If there was some bug in Xcode 11 that caused a package to be mis-built in some way, and rebuilding that package with Xcode 11.4.1 would fix it, we can do that by revbumping the affected port, we just need to know which port(s) to do that to. If you have any information about what specifically is wrong with the affected packages that might be helpful as well for possibly identifying other affected packages.

[ryandesign (Ryan Carsten Schmidt)]

After trying to rebuild various rdependencies of i686-w64-mingw32-gcc-nothreads with no change, in the end I think only mpfr needs to be rebuilt to fix this problem.

Our package of mpfr @4.0.2_0 for Catalina was built October 29, 2019, at which point the latest version of Xcode was 11.1, so that's probably what we were using on our build server, though we may have still been using 11.0.

If it really is a case of an old Xcode 11 building mpfr incorrectly, then we should not only increase the revision of mpfr but also ensure that a recent enough Xcode is being used. I don't know what the earliest version of Xcode 11 is that builds it correctly, but Gcenx reported success above on February 28, 2020, at which point the latest version was Xcode 11.3.1, so we could use that as the minimum:

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

There is an alternate ​pull request that attempts to solve this problem.

[ryandesign (Ryan Carsten Schmidt)]

Thanks. I see you lowered the minimum Xcode 11 version to 11.2. Did you do some test builds and verify that when mpfr was built with Xcode 11.2 i686-w64-mingw32-gcc-nothreads would build without crashing?

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

Yes.
i686-w64-mingw32-gcc-nothreads seems to build with no changes if mpfr is built with Xcode 11.2.
If mpfr is built with older versions of Xcode, -fno-stack-check also seems to fix the problem.

[ryandesign (Ryan Carsten Schmidt)]

Great, thanks. Does the stack check issue only affect Catalina? What happens if a Mojave user has Xcode 11.0 or 11.1?

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

If I recall correctly, -fno-stack-check is the default for OS versions prior to macOS 10.15, regardless of Xcode version.

[Gcenx]

Sorry @ryandesign for not responding to this, somehow gmail was marking the emails as spam....

As @MarcusCalhoun-Lopez says -fno-stack-check is default below Catalina.

The package issues were all built using Xcode11 initial release anything built after Xcode11.2 don't have these issues.
