iOS build fails at AOT compile

I am trying to build for iOS using the latest beta and keep seeing these errors. I have tried tweaking the build stripping settings and .NET Api level, but to no success. My project compiled fine with the earlier beta build 8, so I'm not sure what has caused this issue to pop up. Any ideas are much appreciated!

Cross compilation job Assembly-CSharp-firstpass.dll failed.
UnityEngine.UnityException: Failed AOT cross compiler: /Applications/Unity/Unity.app/Contents/PlaybackEngines/iossupport/Tools/OSX/mono-xcompiler --aot=full,asmonly,nodebug,nimt-trampolines=4096,ficall,static,outfile="Assembly-CSharp-firstpass.dll.s" "Assembly-CSharp-firstpass.dll" current dir : /home/ExilesU5Beta8/Temp/StagingArea/Data/Managed

I am getting 13 of these in a build. Using Beta 5 b9

Here is an example

Cross compilation job UnityScript.Lang.dll failed.
UnityEngine.UnityException: Failed AOT cross compiler: /Applications/Unity/Unity.app/Contents/PlaybackEngines/iossupport/Tools/OSX/mono-xcompiler --aot=full,asmonly,nodebug,ficall,static,outfile="UnityScript.Lang.dll.s" "UnityScript.Lang.dll" current dir : /Users/MEH/ZombieBike/Temp/StagingArea/Data/Managed

Same "stderr: AOT : Unknown argument 'ficall'." Not sure what this is.

 

How do I report this as a bug. Its blocking form making iOS builds?

 

Same issue. Can't build... really need a response on this one, completely stuck

 

The solution is very simple. Submit a bug report:
http://unity3d.com/BugReportingFAQ

 

I submitted, did you both also? so it can get some priority vote it up

 

What's the link to your bug?, I didn't include a project because mine is so big. I'll vote yours up coreyldin.

 

I submitted a bug as well. I found that if I changed script execution from "fast but no exceptions" to "slow and safe" I was able to build successfully.

 

Boom that was it. Looks like slow and safe gets around this. The bug is def with fast and no exceptions.

 

This is a beta product... you get no priority bump. Bugs are expected... just file the bug reports.
