I'm not sure I trust the output of -S printdiff, there are some cases
it doesn't seem to "guess" right. I wish I or someone one could fix but
but we can do its work manually. Can you try something like:

set TMPDIR = "x"
bitbake -S bar
rename the recipe
set TMPDIR = "y"
bitbake -S bar

then

"ls tmp-x/stamps/xxxx/bar"
"ls tmp-y/stamps/xxxx/bar"

and see which tasks change signature. Then run:

"bitbake-diffsigs <sig A> <sig B>"

and see if that makes more sense?

Cheers,

Richard
