I suspect the problem is caused by this commit: http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=3a8312d00e59b50e76121cd512177e999c18b06d

I've also added a bug report on the emacs side: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=19645

Yes Stefan warned that we should expect failures in the next days
because he is actively modifying eieio, thanks for reporting the bug

I had this issue, but it appears to be fixed now with 20150121.937 and emacs master (commit 59e7fe6). Thanks!

@thierryvolpiatto Yes, fixed. Thanks!
