Hi Greg,

could you please provide a bit more information? Which code are you compiling? 
Master from GitHub?
Which compiler version are you using? gcc 6?
Which ObjC runtime are you using? And are the ObjC runtime headers the ones 
from the runtime you link with?
And most important, are there any warnings from the compilation?

I would expect this to be caused by a mix up of ObjC runtimes. Perhaps left 
over headers while you switched back to the gcc runtime.

Hope this helps,
Fred
