A gentoo update in the last few days seems to have nixed vim. I see that Bug #293631 (referenced in the URL) seems to have had similar problems in the past so I'll try and use that bug report as a template in the hope that I convey enough pertinent information. Some points to bear in mind: 1. Attempting to rebuild didn't help. 2. Attempting to rebuild with USE="-python" didn't help. 3. The update I allude to above did rebuild the compiler The attachment that follows contains various logs etc. Thanks.

Another bit of information : If I delete $HOME/.vimrc, then vim is able to launch without aborting. This doesn't seem to have anything to do with the content of the file - I get the abort even with an empty .vimrc.
vim_src_prepare() was not being called again. I fixed this before and fixed it for this version too.
