  1. fix: Skip trailing garbage frames after _start 

    Our lack of support for `DW_CFA_undefined` can lead to conditions where we read a garbage return address via CFI. We observed this specifically for the `_start` function as generated for some linux compiler/libc combinations.

This works around this by explicitly skipping a trailing unmapped frame following `_start`.
