Why can throwing across DLL boundaries be fragile?
PICTURE THIS: RAG CHATBOT
Simple meaning
Different CRTs and exception personality routines may not match.
WHY — ABI instead of guessing?
Why interviewers care about ABI:
on ABI.
the situation, the default choice, and one exception - that reads as experience.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Different CRTs and exception
personality routines may not match.
- 2I keep exception boundaries
inside one module or use error codes at APIs.
- 3Matching runtime settings is
mandatory if you throw across.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
Here's a short line you can speak, broken into clear beats:
Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
Different CRTs and exception personality routines may not match. I keep exception boundaries inside one module or use error codes at APIs.
