Changes between Initial Version and Version 1 of Ticket #20861, comment 7

initial	v1
1	1	Seems that get_permalink for custom post types depends on get_extra_permastruct in wp-includes/rewrite.php and acts wrongly if the target custom post types was registered with the "with_front" parameter (or without: with_front=1 is default).
2	2
3		get_extra_permastruct relies on it's internal var extra_permastructs~~['post-type-name']~~ which doesn't get updated to the new context when calling switch_to_blog.

4	4
5	5	So all permalinks fetched after switch_to_blog get constructed in the rewrite-context of the original blog calling the function - not the blog context the programmer switched to.
