iOS XCode compile error: unable to execute command: Segmentation fault: 11

clang frontend command failed due to signal (use -v to see invocation)
xcode segmentation fault: 11
clang segmentation fault: 11
jenkins segmentation fault 11
apple clang error xcode 11

I have a project which compiled perfectly in the past, but after the last xcode update (6.3.2) I get a compile error whenever I try to run it directly on a device. Building and Running it in the simulator works fine. The Archive function works fine as well. But no matter what device I connect or what iOS version the device is running, I always get the same compile error:

  1. It shows me random files that I'm supposed to submit to the bug report.
  2. I haven't made any code changes from a working version to the version causing the current problems and I even reverted to an earlier version which is live and running in the Appstore but still the same error.
  3. I have deleted xcode and installed again trough the app store
  4. I tried making changes to my code to maybe pinpoint any problems but since the source file of the problem changes every time, I don't really think anymore that it has anything to do with my code.

This is driving me mad. Any help is much appreciated

I tried to add the paypal framework to my iOS Project (Using Xcode 7.2 and Objective-C language), When building it is not giving any error, but when I try to archive the Project and trying to make the IPA, I am getting that Error

unable to execute command: Segmentation fault: 11

Screenshot:

After huge trying I have disabled the Bitcode in Project's Target->Build Settings->Enable Bitcode. Now the build can be achieved. Please check the following screenshot.

I found a fix for my problem:

I'm using a virtual machine and opened the project directly in the shared folder. I moved the project to the documents and now it works!

We've just realized that segfault was caused by invalid unicode characters in our sources.

I can test on my iOS device and simulator perfectly fine, but as soon as I tried to archive it.

I had the exact same problem. In my case I looked at the offending file and played around with it. I was able to resolve the error by commenting out a giant NSDictionary declaration:

 NSDictionary* glyphNameToUnicode = [[NSDictionary alloc] initWithObjectsAndKeys:
                                    @"A", @"A",
                                    @"\u00C6", @"AE",
                                    @"\u01FC", @"AEacute",
                                    @"\u01E2", @"AEmacron",

This thing had probably 300 lines maybe more. Instead I moved the declaration into a file and loaded the dictionary from the file. Not sure if that helps, but in my case those files were not random...

Its deff a bug with xcode though...

Apparently it was a bug in my Xcode version. Had to revert to an old one and everything worked again. With the newest update everything was working ok again.

  • Did you do this? "diagnostic msg: PLEASE submit a bug report to developer.apple.com/bugreporter and include the crash backtrace, preprocessed source, and associated run script. clang: note: diagnostic msg:"
  • No, not yet. Wanted to know if it's just simply my fault first.
  • please change your compiler GCC instead of LLVM ,,and try.
  • Picciano is correct: you should always report a compiler crash, which can’t be your fault. (Though as user2444342 notes, you can sometimes work around the crash by fiddling with your code.) VD Patel: GCC was removed from Xcode years ago. (The last GPL 2 version was getting quite old, and Apple can’t use any GPL 3 version.)
  • will there any issue if I put it in app store?
  • Hi @BhavinRamani I have tried to make that on 2-3 projects for Google Sign up by WebView, and paypal framework, But till now app store testers did not respond me anything for that, I mean still now the App can be lived by that change. I do not know later on they change anything or not.
  • Your answer helped me. I got error while archive the project not in run time after integrated facebook analytics in my app. Thanks for your reply. 😀
  • It helped me. Fresh new project, Xcode 7.2, OS X 10.10.5, archiving was lead to segmentation fault. Disabled bitcode, and oops, archiving done.
  • Closing and reopening project worked... I feel dumb, but thanks!
  • Thanks, this put me on the right track and I asked the moderator to undelete it. See my answer (Sept 29, '16) for details.
  • Thanks @JoshuaNozzi for understand it.
  • Incremental did not work on device, but Monolithic works fine. So I used No for debug and Monolithic for Release.
  • It helped me too. But after a while having the same problem with Xcode 7.3.1.
