Another thing I noticed: if there is a valid ~/.config/emacs/init.el,
emacs -nw -Q works fine. If I mv ~/.config/emacs{,.bak} I see the
problem. I don't have a /etc/emacs folder either, so maybe that helps
you in reproducing the issue?

This feature didn't do anything right after the start, but after closing
the *scratch* window, and then trying again in the new *scratch* I got:

Breakpoint 1 at 0x137c7f
.gdbinit:1239: Error in sourced command file:
No symbol "defined_HAVE_X_WINDOWS" in current context.
[snip: other instructions]
And after

    (gdb) run -Q -nw

I get: 

    Breakpoint 3, 0x00000d95326ee646 in Fsignal ()
    No symbol "error_symbol" in current context.

Also after each consecutive continue, until emacs starts normally,
without triggering the error.

So I think something is missing here. But what?
