Looks like our new clang diagnostic from r210293 has caught a potential issue in compiler-rt which is now breaking the build due to -Werror:<br>

Can you confirm that the stack frame report is legitimate?<br>
<br>
Assuming it is, you'll probably want to either fix the function or relax the byte limit passed to clang in your build system.<br>
<br>
Let me know if I can help.<br>
