Comment 4 for bug 1229334

No problems, actually it was my fault mention the merge discussion and skipping making it clear that I decided for the official UltiSnips.

I'm able to reproduce this problem in a fresh new installation of gVim on Windows, with an empty .vimrc (_vimrc on this OS) and renaming the ultisnips directory to .vim (vimfiles on this system). The empty .vimrc is significant for some options, as 'compatible'.

Maybe my explanation isn't very clear; on step 3, after inserting "te", it is necessary to hit Ctrl-p twice, in order to trigger word completion. Ctrlp is is the default, as explained in :h 24.3 and :h i_CTRL-P, but maybe you have some mapping that overwrites it.
If you still don't see any completion menu it is possible that you have set 'cot' option to something different from the default (which can be restored with :set cot&).

Then I think the expected behavior is "temp2", as show below step 3. The problem I see is that when option 'cot' is changed the text gets wrong when you press Ctrl-P more than once - which leads to output after step 4.
