Sorry! There's the code.

It seems the problem is more complicated. You're supposed to put your
custom phrases in a plain text file, one phrase per line, which file is
pointed to by the variable wubi-phrases-file. When
`wubi-load-local-phrases' is called, it turns that text file into an .el
file, the name of which is pointed to by wubi-phrases-file-el. So far as
I can tell, emacs segfaults when these two files have the same name, ie:

(setq wubi-phrases-file "~/.emacs.d/my-wubi-phrases.txt")
(setq wubi-phrases-file-el "~/.emacs.d/my-wubi-phrases.el")

I moved "my-wubi-phrases.el" to "my-wubi-phrases-short.el", to start
testing if a shorter file would prevent the crash, only to find that all
it took was re-naming the file to allow it to load safely.

So now it seems highly likely that the crash I thought I was
experiencing isn't at all the one I'm actually experiencing. I'll
happily do whatever's necessary, but I have the sense I'm barking up the
wrong tree.

I'm still sending this email from the arch emacs binary, but here's the
data from report-emacs-bug from the git emacs that crashes:
