Swift command line tool runtime crash dyld: Symbol not found: __pthread_atfork_child

When I build any swift command line tool it always crashes (Thread 1: signal SIGABRT) right after launch with:

 

 

dyld: Symbol not found: __pthread_atfork_child
 Referenced from: /usr/lib/libSystem.B.dylib
 Expected in: /usr/lib/libSystem.B.dylib
 in /usr/lib/libSystem.B.dylib 
Program ended with exit code: 9

 

 

This happens to any command line tool I build. Even when I build the xcode command line tool template.

 

Reseting the mac to an earlier time machine backup fixed the issue for a day. Then it came back for no reason.

However I am able to build command line tools using the swift cli and package manager.

 

I’m using Xcode 8 on macOS 10.12.5
