◆ SanitizeDebugTrapReasonKind

Enumerator
None	Trap Messages are omitted. This offers the smallest debug info size but at the cost of making traps hard to debug.
Basic	Trap Message is fixed per SanitizerKind. Produces smaller debug info than Detailed but is not as helpful for debugging.
Detailed	Trap Message includes more context (e.g. the expression being overflowed). This is more helpful for debugging but produces larger debug info than Basic.
