Hi @eskimo thanks for your timely and helpful response! The article you shared led us to our finding which points to a third-party static library that we use. We will contact the owner of the library and see if they can look into the issue since we don't have the source code of the library.

Hi @eskimo I am following up to see if you have thoughts on my comments to your response? Also adding more context about the crash Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000000 Exception Codes: 0x0000000000000001, 0x0000000000000000 One more question, based on the exception type, I am also curious if you know how to get more details about what 'exchg_registrar::exchg_registrar()' is trying to do and what arguments it's trying to dereference when it got hit with a KERN_INVALID_ADDRESS. Like I mentioned in my previous comments, even though exchg_registrar() is shown as if it's called from our app 'fieldwire', it's not written by us so I am not able to learn more about 'exchg_registrar::exchg_registrar()'. Let me know if you need any other details about this issue, thanks!
