App Crashing (EXC_BAD_ACCESS) only in RTL Languages like Arabic - ios

Question

App is crashing with EXC_BAD_ACCESS exception only in RTL mode whereas the app is working fine in LTR mode. I'm running the app by forcing it in RTL mode as below,
Edit Scheme -> Run -> Option -> App Language -> Right to Left Pseudo Language.
It is crashing in UIApplicationMain with following stack trace

I have enabled Constraint Error Breakpoint , Exception Breakpoint and Run Time Issue Breakpoint but have no luck in finding any clue about the issue. Have used instruments to find memory leaks but had no luck there too since it showed as no leaks.
So from crash logs it is clear that app is crashing coz of something went wrong inside Autolayout engine (which may be coz of some contradicting constraints) and I can't check all the constraints since app has huge number of them. How can find the root cause of this crash and fix this issue.
I would appreciate any help in finding the root cause of this crash issue.
