Fair enough. Thanks for looking this.

I can confirm that https://projects.archlinux.org/svntogit/packages.git/tree/trunk/clang-3.7.0- add-gcc-abi-tag-support.patch?h=packages/llvm is causing the crash. The patch was taken from http://reviews.llvm.org/D12834 , https://llvm.org/bugs/show_bug.cgi?id=23529 .

If that patch was not applied upstream, then this is not an actionable bug for us. If you care about gcc_abi attribute support, follow http://llvm.org/pr23529 instead.

(the compilation is possible, just run the compilaton once again)

Now I'm not possible to compile UE4 by compiling again (it worked last time when I tried)...

I think that this patch causes the crash: https://projects.archlinux.org/svntogit/packages.git/tree/trunk/clang-3.7.0-add-gcc-abi-tag-support.patch?h=packages/llvm but I'm not sure. I'll recompile clang+llvm without this and I'll try whether it crashes. See: https://llvm.org/bugs/show_bug.cgi?id=23529 http://reviews.llvm.org/D12834

The "test-a50d6e.sh" doesn't crash anymore on Arch/Manjaro Linux (clang+llvm 3.7.1), but the "Module-32cf37" from http://sendfile.es/pokaz/630150---qw5t.html still crashes on Arch/Manjaro llvm+clang package. This test (Module-32cf37) doesn't crash on Arch/Manjaro with llvm+clang downloaded from http://llvm.org/releases/3.7.1/clang+llvm-3.7.1-x86_64-opensuse13.2.tar.xz . I'm able to compile UnrealEngine with "clang+llvm-3.7.1-x86_64-opensuse13.2.tar.xz" without any problems, but using clang+llvm from distribution package I've got a crash (the compilation is possible, just run the compilaton once again).

Arch Linux uses additional patches which probably causes the crash, please take a look at https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/llvm

This does not crash with a recent clang.

Exception specification handling has changed since 3.7, and I think this has been fixed.

It is not fixed. Just tried to compile UnrealEngine 4 on 3.7.1 and it crashes with exactly same messages on 5-10 files of 872.

It is better to reopen this bug and to investigate where is the problem. It looks like minimal example is difficult to make but this does not make this bug fixed because the problem still exists and annoys people.

I am experiencing this on Fedora 23 with Clang 3.7.0-4.fc23. I don't think this is simply a Arch packaging issue as I am getting the exact same crash when trying to compile UE4.

llvmbot commented 8 years ago

Ok, now I tried LLVM+Clang 3.7.0 downloaded for openSUSE 13.2 from LLVM page and it doesn't crash (test-a50d6e). So this is Arch Linux packaging problem...

I was using the Ubuntu 3.7.0 binary downloaded from llvm.org. Also a 3.7.0 that I built myself from tags/RELEASE_370/final as reported in the console log. I didn't see anything labeled "Minjaro" on llvm.org, so I don't know where your compiler came from.

My compiler came from Arch Linux official package. It is built with the following patches:

On Ubuntu 14.04, I was unable to reproduce the crash. I tried test-a50d6e.cpp and several of the modules from comment 6.

I don't know what to suggest, sorry. I'll leave the bug open though.

Are you using the same version of clang as the one packaged on Arch? Arch is a bit out of date (using 3.7). Did you use 3.7.1? If it crashes with 3.7 but works with 3.7.1 I would be happy to mark this as resolved.

Here are the related files that clang asked me to attach from the console log I submitted earlier. I had to upload them to an external server, cause they are 9 MB after compression:

Crash with libc++ I can also crash clang 3.7 with libc++ 3.7 only by including iostream (see attachment test-a50d6e.tar.gz).

Console output from segfault I think I am experiencing the same bug, a segfault when compiling Unreal engine.
