Please ask about unclear parts, but maybe the backtraces are good
enough.

I got one.  [ I was lazy and was just creating a new frame at the
beginning of my init file when repeated loading was detected and used a
breakpoint on x_create_frame - because I did not want to learn about
conditional breakpoints for now. So please don't get confused because of
the innermost backtrace frames. ]

What I did: I have started the debugged session, then edited and
recompiled my main config file "~/gnu-emacs/.gnu-emacs.el" (which is
loaded from "~/.emacs") from a separate session, and then did C-h f
some-function-defined-in-my-init-file RET in the debugged session.

(function-documentation 'some-function-defined-in-my-init-file)
 --> ("/home/micha/gnu-emacs/.gnu-emacs.elc" . 291847)

if that matters.
