Hi all, Firebase statistics show that some crashes seem to occur suddenly. Can you give me some suggestions? Users also meet the following requirements: iOS18 and above RTL language From the stack frame, the crash occurred in the transition animation project, but I did not reproduce this stack frame A very small number of users can experience it twice The crashed page is relatively complex, and it is a mixture of auto-layout and frame I retrieved some other articles, but they don’t seem to be the same problem https://developer.apple.com/forums/thread/693118 https://stackoverflow.com/questions/56027014/collectionview-crashing-in-nsisengine-after-a-few-scrolls Thank you for reading, looking forward to your reply ；) CoreAutoLayout: _engineVar_rawRemove

Crashed: com.apple.main-thread 0 Foundation 0x2bd25c specialized static NSDecimal._integerDivide(dividend:divisor:maxResultLength:) + 1996 1 Foundation 0x2c1c0c specialized NSDecimal._divide(by:roundingMode:) + 2432 2 Foundation 0x372710 static NSDecimal./ infix(_:_:) + 64 Crashed: com.um.positions.fiber.queue 0 Foundation 0x2bdc94 <redacted> + 1996 1 Foundation 0x2c2644 <redacted> + 2432 2 Foundation 0x372804 $sSo9NSDecimala10FoundationE1doiyA2B_ABtFZ + 64 After iOS18, some new crashes appeared, but they never appeared before iOS18. How to avoid such crashes? I checked the API documentation and there is no relevant modification, https://developer.apple.com/documentation/foundation/1409398-nsdecimaldivide However, I parsed iOS_22A5326g/../Foundation.framework/Foundation, and found that this EXC_BREAKPOINT is newly added You can reproduce it with the following code: let a: Decimal = .greatestFiniteMagnitude let b: Decimal = .greatestFiniteMagnitude let c = a / b // if < iOS18, c = 1. if = iOS18, will crashed ;< print(c)
