Something I wondered myself the last time I was looking at this (over a year ago), is if this couldn't be implemented using more robust and platform independent semantics by tracking down the required files throughout the data layout (like for vector, you're looking for 3 pointers in specific order, but you don't assume anything about how their nested). 
And then show the raw data layout if you can't find what you are looking for. That would avoid crashes.

That's not exactly the same as what you're saying. But it's a bit in the same design space I guess.
