It has been observed that crash handler can now corrupt memory during __cxa_demangle (from libc++). Repro steps listed here are just one of possible ways to trigger it, very similar crashes have been observed in the wild with servers (see attached logs).
More info: _cxa_demangle() called on this symbol: _ZNK10TTupleImplI16TIntegerSequenceIjJEEJEE10ApplyAfterI21TMemberFunctionCallerI16SConsoleInputBoxMS5_FvRK5FTextN11ETextCommit4TypeEEEJS8_RSA_EEEDTclfp_spcl7ForwardIT0_Efp0_EEEOT_DpOSF seemed to corrupt the memory around GLog. Assumption that it runs out of crash handling stack turned out to be incorrect :/
1. Build DebugSet (make DebugSet)
2. Run UE4Editor-Linux-Debug and create a blueprint project
3. Type "debug crash" and watch closely the editor console
4. Observe that crash will happen before the callstack is printed and CRC will not be run
I am not able to find world outliner how to enable it?

There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-34450 in the post.
