Hi Paul,

That’s because we use ‘--strip-debug’ and not ‘--strip-all’ (in some
cases, the latter breaks binaries in weird ways, hence the conservative
choice.)
However, you can see in the list of ELF sections reported by “objdump
-x” that there’s no .debug* section—i.e., binaries contain the symbol
table, but not DWARF debugging info, which is far larger.

I don’t think it makes any difference.

Oh sorry, I had forgotten we already had this. This is perfect!

I let Dave answer on this part.
Thanks,
