I decided to do a little bisecting to see when running

  ./src/vim -u NONE -i NONE -N --cmd 'set modified' --cmd 'if &modified | q! | else | cq | endif'

would start breaking, using HEAD as known bad and 7.4.963 as known good.
Interestingly, the first step saw Vim outright crash when it started up.
However, the core was actually usable by gdb and also went away when
compiling without --enable-perlinterp!

That pattern continued and Vim patch 7.4.1065[0] appears to be what
broke Vim for kFreeBSD.
