I have also confirmed them with address sanitizer. 
For example, The ASAN dumps the stack trace as follows:

ASAN:DEADLYSIGNAL
=================================================================
==8794==ERROR: AddressSanitizer: FPE on unknown address 0x000000403810 (pc

AddressSanitizer can not provide additional info.
