Xcode 10 freezes while creating dSYM for GStreamer

Status:Open Resolved:
Product:Xcode Product Version:10.1 (10B61)
Classification:Bug Reproducible:Always
With Xcode 10 the creation of dSYM of a project, which contains GStreamer does not finish.
This eventually lead to rebooting of the OS.

We noticed in activity monitor that "llvm-dsymutil" uses abnormal amount of memory and CPU.

With Xcode 9.4 this problem is not observed!

At the moment we know only two workarounds:
1. Use Xcode 9.4
- since we supposed in the near future Apple requires to use Xcode 10, this is just a temporary workaround

2. Disable dSYM
- this has the disadvantage, that crash-reports can no longer be properly analysed...

Steps to Reproduce:
1. Download GStreamer (https://gstreamer.freedesktop.org/documentation/installing/for-ios-development.html)
2. Create project and integrate GStreamer.framework
3. Archive the App for the AppStore or change the building to dwarf with dsym when you build for simulator

Expected Results:
Build finished normally with output of dSYM

Actual Results:
- Build does not finish
- instead in activity monitor one can see that "llvm-dsymutil" starts using abnormal amount of memory and CPU

Xcode 10.1 (10B61)

It looks like this is similar to https://openradar.appspot.com/45324895 (there VLC was used)
