First attempt building our code base in xCode7 for iOS -- getting a fatal error in the backend running ProcessPCH++. I've included the output below.
Is there any further diagnostic details we can turn on to provide information? This is a LARGE codebase, and the chances of me being able to supply it to Apple as-is is zero.
COMPILER ERROR
==============
fatal error: error in backend: Broken module found, compilation aborted!
clang: error: clang frontend command failed with exit code 70 (use -v to see invocation)

Target: arm-apple-darwin14.3.0
Thread model: posix
clang: note: diagnostic msg: PLEASE submit a bug report to http:/ and include the crash backtrace, preprocessed source, and associated run script.
