In-Reply-To: <20070513215012.3A13614297@owie.lan> (message from Ryan Yeske on Sun, 13 May 2007 14:50:12 -0700 (PDT))
I have a useful backtrace for this problem, but I can't really figure
out why it happens. The short story is that the problem is caused by:
(setq load-source-file-function 'load-with-code-conversion)
in loadup.el, this causes insert-file-contents to be run from mule.el,
at which point when we are returning from insert-file-contents,
something corrupts the stack, so that we cannot return, and we
segfault badly because of it.
If one simply doesn't set load-source-file-function, we continue quite
far until trying to load faces.el, at which point temacs complains
about requiring 'cl.
I have attached a (messy) backtrace; this is right at call to
insert-file-contents in mule.el on line 78, and we are just returning
from insert-file-contents. Does anyone know what is going on?
