It isn't really a bug.  It's just that some functions are designed as
user-level interactive commands -- they do more than you want when you
use them in a program.

You're not the first to hit this problem :-) and the docstring for
`beginning-of-buffer' does warn about it :

| Don't use this command in Lisp programs!
| (goto-char (point-min)) is faster and avoids clobbering the mark.
