This could be a minimal stack trace that only includes functions up to the previous compartment transition. Also if it's optional it might be feasible to require -fno-omit-frame-pointers to use this which would simplify walking the stack since we wouldn't have to parse .eh_frame_hdr stuff.

Using frame pointers may or may not be feasible depending on whether some dependencies like libc or ld.so are usually built with them or not.
