Re: Help debugging a backtrace

[Kaushal Modi]

Thanks for this tip:


*BTW, `load-history' is in chronological order, the position of thefaulty
entry in the list might give some hints as well.*

The problem is not yet resolved, but looks like I made some debug progress.

If I launch emacs with my config, this problem exists (of course).
*But if I launch "emacs -Q" or "emacs -q" and then evaluate my init.el,
this problem goes away.*

Below is a part of load-history value after I started emacs with all my
config commented out except for the package requiring part.

Looks like something is messed up in emacs autoloading?
- lisp/thingatpt/elc is loaded
- Then lisp/help-fns.elc is loaded
- Then something is loaded that tries to require finder-inf
- Then lisp/term/xterm.elc is loaded

*Where can I find the order of where these inbuilt packages are loaded?
>From what I see, that order is not alphabetical.*
