"emacs" and "emacs -q -l ~/.emacs.elc" behave differently

[mandar.mitra]

Hello,

I was under the impression that running emacs and running 
"emacs -q -l ~/.emacs.elc" would be the same, but I'm getting 
different behaviour in the two cases. 

Specifically, "emacs" hangs (100% CPU, non-responsive) when displaying a
particular email in message mode, but "emacs -q -l ~/.emacs.elc" displays
the message without problems.

Emacs version:
GNU Emacs 24.1.50.1 (i686-pc-linux-gnu, GTK+ Version 3.2.0) of 2012-09-19 on litembilla, modified by Debian

(emacs-snapshot installed from Damien Cassou's ppa on Lubuntu 11.10)

Thanks for any tips,
mandar.

Generally speaking, no. The sequence of actions will be different.
Take a look at the "Startup Summary" node of the Emacs Lisp Reference
Manual.

Thanks for the pointer!

More details in case anyone else finds this useful: init file loading
happens in step 12, and "command-line options that were not handled
earlier" (presumably this includes -l) are processed in step 21. In
between, it does a bunch of stuff like calling package-initialize,
after-init-hook, etc.
