I just checked, and the binary for the 'ls' command is what's called 'pure
code'; i.e. the instructions are in a separate (potentially shared) block of
memory from the process' data (un-shared).
I don't recall off the top of my head whether the location of that shared
block of memory is in the per-process swappable kernel data (which is included
in the process core dump). I'll check tomorrow, when I'm not sick as a dog
(pretty miserable right at the moment).
It would be east to mod the OS to print all that info when that illegal
instruction trap happens - but that will change the size of the OS, so will
probably change the location the process is at; so that might cause the
symptoms to change. Ditto for recompilling 'ls' to make it a unified blob.

:-) Don't worry, we'll nail it!
