bot linking libclang_rt.tsan_osx_dynamic.dylib

Hello,

I am new to running XCodeServer and am experiencing differences between builds created locally on a developer laptop compared to builds created by my build bot...


I have a project which links together a number of proprietary frameworks, provides a bit of application delegate logic and some resources.

When I archive the project (using my 'release' configuration) on my development machine (my laptop), I get a pristine, fresh, optimized app.

However when I run my xcodeserver build on the release configuration the output is not so optimized and clean... in fact it runs a bit sluggish and when I quit it generates a Thread Sanitizer report (which doesn't happen if I build from my development mac).


Threading issues aside, why is my release build, when integrated on the xcode server (using xcode 8.3.3), linking against libclang_rt.tsan_osx_dynamic.dylib ???

I cannot find anywhere to disable this "feature" (though I never enabled it for my release builds!!).


Any help would be greatly appreciated,
