This is a common crash on Mac in the 4.16 release.
The callstack is fairly generic , so it shares similarities with other Jiras such as [Link Removed] and [Link Removed], but this issue is different.
With Xcode 7.3.1 ([Link Removed]) installed to /Applications/Xcode.app, download attached 8650_51197943.metal shader to Desktop, then execute following commands from the terminal:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/usr/bin/metal -ffast-math -Wno-null-character -std=osx-metal1.1 ~/Desktop/8650_51197943.metal -o /tmp/ShaderIn6030DA82FF4D1DF0CE2788BB36EED60F.o /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/usr/bin/metallib -o /tmp/ShaderIn6030DA82FF4D1DF0CE2788BB36EED60F.lib /tmp/ShaderIn6030DA82FF4D1DF0CE2788BB36EED60F.o
First command will succeed, but the second one will fail with the metallib: Unexpected token !r error.
