--- Comment #4 from Philip Nilsson leffeman@gmail.com 2009-06-16 17:40:27 --- It's still around.
I wrote a few test applications three months ago which gave me the same errors and concluded it's because of the known problem with code injection (bug 13915 might be the same or related if true). A page on the Wine Wiki[1] has some information under the TODO heading, the linked thread[2] is worth reading.
