Hi,

sorry for the typo.

I'm coming upon from functions which exchange-point-and-mark in order to 
get the string found displayed. Seems it's the setting of the mark, 
which triggers the bug.

If the last line is changed into

(kill-new (buffer-substring-no-properties 200 203)) asdf

evaluating it before "asdf", push-mark, down one or more line, region is 
active, yank, "asdf" is inserted.


Which follows the setting of select-active-regions, please see my 
posting to emacs-devel.

Basically it's a design-flaw IMHO.

Thanks

Andreas
