2016r4 Runtime Error

Checking code with the check code button in most of my projects gives me a runtime error:

Runtime Error

Location: Common/SpawnCompiler/
Condition: me->extra->code->IsObjectCode()

Two buttons; ‘Continue’ and ‘Quit’ both quit the IDE unexpectedly.

Running on MacOS 10.12.1

Already filed a case as well: 46156

I’ve installed 2016r4 this morning and already experienced several IDE crashes. Not saving project changes on exiting also often crashes the IDE.

Anyone else experiencing diminished stability with the IDE? Any solutions?

Yup, crashing when closing a project, resinstalling r3 from 2016
