That Crash is triggered immediately while Start App.

I Found Some Crash Point :

1. Some .pb.cc files (from .proto files)
2. Trying "AddSymbol" / "AddDescriptors" (in "generated_message_reflection")
3. If blocking "AppDescriptions" Func, Chash has gone. (but Protobuffer System is also blocked)

so. What can i do next step?
I can not upgrade Protobuffer version & UE Engine version (because My Project's Settings)
(but. i can combination in new version if that issue is solved after Some newer version from my version)

Also, Other OS are not trggered Crash. (especially linux / Andriod System), and Xcode Debug Envioment. (using .app file)

It Just *.ipa (for Distrubution app...)
